My older sister was real squeamish about bugs and stuff. Once when she was getting ready for a date, I told her I had seen a huge ugly bug on the screen of the front door. I then told her that the bug was gone but it looked like it had laid some eggs all over the screen. She froze with the curling iron in mid-air, and turned white as a sheet. Then she started trying to bribe me to get rid of them before her date came.
(why would I want to get rid of them after I went to the trouble to put them there in the first place?) 
I had taken some Kraft sliced cheese, and squished it into the screen. It made these neat little clusters.
She wouldn’t even go look at them, which kind of defeated the purpose of doing it. But my Dad saw them, and agreed that it must be some kind of insect larvae, (he was serious). My sister called her date and told him to come to the backdoor when he picked her up.
My Dad got curious and started poking the eggs, then he got some on his finger and sniffed it, then he looked right at me and went into the other room before he started laughing.
My brother shoved my sister in the bathroom, tied the door shut, and turned the heat up to 95 or 100 degrees. Sadistic little fucker.
After watching American Werewolf in London with my 6 year old little brother, (I was 13) I put a leftover halloween werewolf mask on (you know the ones that slide over your head, they have lots of detail and are bloody and gross…) and I crawled into his closet. The closet had saloon doors on it and it faced his bed. I waited a good 15 minutes until he was almost fully asleep. Then I started scratching very softly on the door. I could see him through the crack. The second he opened his eyes and looked at the closet, I threw the doors open and pounced on the foot of his bed!! :)
He screamed and basically flew into my parents room, his feet never touched the floor. This was in 1983 and I’ll never forget the look on his face. Now he is 25 and I still tease him about it.
We would give these treats to our dog that he basically would suck on while and drop, which resulted in lots of broken pieces of these treats all over our carpet.
Once, my sister started yawning slowly. On the spur of the moment, I felt on the floor, found a bit of treat (probability was with me on that one), and whipped it at her mouth. It didn’t quite go it, but got stuck in the corner of her mouth.
I was laughing so hysterically that I was powerless to stop her from stuffing handfuls of bits into my mouth as I lie on the ground convulsing. Quite possibly you had to be there, but I still have to laugh out loud thinking of that, 20 years later.
One summer, I began getting up in the middle of night, sneaking over to my sister’s room, and whipping a penny as hard as I could into it. She would complain the next morning about the strange banging noise waking her up, but never associated the odd penny or two she’d find on the floor with it.
My oldest sister would steal my other (the middle) sister’s diary and read it into a tape recorder with me acting as an accomplice. She would then replay the tape right outside my sister’s bedroom. My sister was horrified over and over again.
We (there’s five of us) also loved turning off the bathroom light when another one of us was in the shower. That was probably the most common mean thing we did to each other.
My sister wouldn’t stop following me around-she was about two, I was probably 8 or 9.
So I tied her to one of her little chairs and went back into our room to read. My mother found her five minutes later and had to duck out of the room because she was laughing so hard.
I convinced my little brother that the watermelon seed he had swallowed would grow inside his stomach into a full sized watermelon and kill him.
Poor kid.
When my younger brother was about 14 years old he farted into the very small downstairs bathroom. He then grabbed my 10 year old sister and threw her into the bathroom and pulled the door closed so she couldn’t get out. He left her in there for about a minute. My sister banged on the door and screamed at him while my brother laughed so hard he could barely breathe. Something about my brother you must understand is that the rank stench of his emissions suggest a diet high in roadkill . . . Since it wasn’t happening to me and I was all of 16 years old, I thought this was pretty funny.
I had my sister sleeping with tape on her nose for a while.
Since both grandmothers have hooked noses because the way genetics works and there was a 50 - 50 chance of getting a hooked nose - I told her that since I already grew into my adult nose ( at 14 ) that she at 9 had not gotten her adult nose yet - she obviously got the gene & her nose would hook.
My sister was very anal retentive about making sure nobody touched her pop in the fridge. I had enough of her watching me every time I wanted to get something to drink (I didn’t like what she drank anyway). One day while my sister was gone a friend and I took one of the cans and poked a very small hole in the top Next we got a hold of a large syringe and needle used for giving injections to horses (my dad owns a drugstore and he carries a few veterinary supplies). By using this we were able to extract the soda contents and then replace it with water. We put the altered can back in with the rest of the six-pack. A few hours later my sister came home and she happened to grab the can with water in it first thing. She took one drink of it and then promptly spat it out. She had no idea that it was just ordinary water. She thought the pop had somehow gotten tainted. She was quite mad at us after we ended up confessing our little stunt.
Barf. My brother did that to me once with a piece of dog kibble!
I can’t think of anything especially nasty I did to him but the worst thing he ever did to me was tell me when I was very young that the boogey man lived in our washing machine. I believed him for years and wouldn’t go into our laundry room alone until I was about 10 years old, even after I realized the boogey man didn’t exist!
my sister would always ask my mother to get her a drink… I would always do it instead… with the condition that the drink comes with a “special surprise”. I would bring her a drink if I was alowed to mess with it and put something in it. I would alway put a grape… or some cerial… or something lame. and she would drink it.
after about 2 years of this game. I stopped putting anything in it. but just clanking around in cupboards alot. and takeing a really long time to bring it. then I would watch her drink it… and laugh really hard.
she became convinced I was putting something unspeakable in it. and would claim that whatever the drink was tasted funny. she would go in depth about how the milk tasted spicy… or her orange juice was too sweet. or how her kool aid tasted like ham. it was HILARIOUS. I got her to start crying a few times. because I would be laughing so hard about her drinking it so carefully… and she would think I was laughing at the evil thing I put in it (always implyed I put dead mice in it… or cat litter… or deer guts)
funny thing is… in the past TEN YEARS I have never ever again put ANYTHING in her drink. but I always smile real big when I bring her one. and my sister every single time… will give complaints about how the drink is too spicy or too minty or how it tastes like chemicals… or smells like blood or something… even after ten years of putting nothing at all in it!!!
My brother and I were at constant battle with each other.
My favourite thing was to pull off his shoe and throw it in the front yard. When he went after it I’d shut and lock the door leaving him outside.
I was scared of the basement when I was about 6. My brother used to hide in the basement for hours waiting for me to go down there. He’d jump out of the shadows and scare the crap out of me. One day I decided my capgun would protect me. Sure enough, he popped out of the shadows with a resounding BOOOOO! Being scared, I pistol whipped him in the face and took out his two front teeth.
When my borther was about 8, I used to hide in his bed, under the covers, when he was out of the room and then jump out. A pretty lame trick which wore off pretty quickly BUT. after I had gotten him used to it, I waited until he left the room and rearranged the pillows and cushions in his room to look like I was under the bed and then hid in the closet. When he came back in the room, I jumped out of the closet the second he pulled back the covers and shouted BOO!. Scared the living daylights out of him.
Bigger brother and I used to wrestle on the living room floor.
The winner would be the one who could place their own mouth fully over the others nose, and then blow.
My older sister was terrified of bugs. One of my favorites was the time I found a potato in the bottom of the bag which eyes that had begun to grow. I saved it until the eyes were long and spindly, and put it in her bed. Much screaming ensued.
I’d climb a tree (almost every day) which hung over the sidewalk she walked down from the bus to home. Dangled rubber spiders, snakes, road kill, etc. from a string. Much screaming ensued.
My older brother, younger brother and I were playing cowboys and Indians (or some such). I captured my younger brother, tied him to the drain pipe in the basement. Forgot all about him for about 2 hours. No screaming ensued. He was a tough kid.
One Saturday night, with nothing much else going on, my older brother was telling me about his wild teenage years and his fun with “recreational chemistry”.
I was cooking a spicy rice dish, and slipped a quarter hit of acid in a spoonful. Just enough to alter things a bit. I asked my brother to taste my rice. About an hour later, I asked him how the rice was.
“What the hell did you give me?”, he asked, staring at the TV. Once he knew, he seemed ok with the fact that his l’il bro dosed him, but I “better not do that shit again!”
kinda long, so i’ll try to condense:
Sister came to visit me. She had never met the girl i was dating (she’s my wife now, only cause i didn’t meet hillbilly queen first!;)). Girlfriend used to run a bar in the middle of nowhere. my sister and me had dinner and i told her there was a real great party “just down the road” and she threw me her keys and said “Lets go!”. I start driving her car and we head out of town. we go thru the next little town. (we both grew up in the area, and she knows there ain’t shit out past Dayton) We keep going, and she starts to ask where we are headed. I assure her over and over “its just a little further”. Well, we’re 40 mile from nowhere and she is starting to get real nervous. When i’m about 2 miles from the bar, i start to mess with her car by pumping the gas pedal and making it hurk and jerk around, shake rattle and roll. I have convinced her that her own car is screwed up!! In the middle of nowhere!! We pull up to the bar and I tell her to go in and ask for directions to a place called the “Chuckwagon” (which was a real place about 20 mile down the road). Sister goes in and asks the bartender (my girlfriend, who has never seen her before) “Where the hells the Chuckwagon!” Girlfriend assumes she is some pissed off wife looking for her husband, and tells her its 20 miles away.
Sister freaks out and heads to bathroom. I come walking in a minute or two later and sit down. Sister comes out steaming, yelling at me for stranding her “in this god-forsaken hell-hole”!
I introduce the two ladys and die laughing. To me, the funniest part was convincing my sister that her own car was broken!
man, did we all get drunk that night!
My brother had the lazy habit of waiting til I went to the kitchen and saying “oh, while you’re up can you bring me … .” Once he asked for a glass of water, so I rattled some ice cubes, ran the water, and brought out an empty plastic cup (an opaque stadium cup). Two steps from him I fake-tripped and threw the cup forward towards him. Man, that’s the fastest I think I’ve ever seen him move!
My friend’s sister was absolutely horrible. She would actually throw something to him, and when he raised his hands to catch it, punch him in the gut. It’s a wonder they still talk to each other. lol.
My little brother was terrified of monsters. I would obtain a blank cassette tape, fast-forward about 15 minutes, then record some growls onto it. Then fast-forward another 5 minutes, record more growls. I repeated this several times, so there were growls every couple of minutes. I would rewind the tape, put it into a player, then place the player undir his bed. I woud press “play” just before he went to bed. Just as he was falling asleep, he would hear the growls and scream for Mom & Dad. They would come running. When he said he heard monsters under the bed, they would yell at him and tell him not to be a baby. Five minutes later, he would yell again. This time, he ususally got slapped. Then for the rest of the night, every five minutes- he woud sit in cold silence, to terrified to move or complain. Years later, when I told him I was responsible for this, he gave a sigh of relief- he was happy to find that it WASN’T all in his head!
