That is so funny, because I actually managed to do this at work. When people started asking me what was wrong with my eye and I explained, I got a lot of suggestions along the same lines. Since I am an incurable blusher, this only fueled the flames. Much as I’d like to turn this into a mysterious box on the side of the highway type thing, it was just paperwork.
Similar to Belrix, I managed to cross the wires, so on the car running, i put the positive where the negative was supposed to go… rather large shock from my little honda…not to mention a few burnt fuses…
Does anyone else follow the Darwin Awards, given to people who remove themselves from the gene pool for the unintended benefit of our species?
I just can not pick as single action or event …
oh, locking the keys in my car (yes, while it was still running), strolling into a dive bar in the most dangerous part of a poor, sleazy town, and shouting over the music to ask the partender to call the police. WHY didn’t I just ask him if he had a slimjim?
Back in my youth, when I was working night shift in a warehouse, we used to sneak up behind each other and cut the belt loops on each others work pants with our utility knives (don’t ask…I don’t remember why, but apparently it was hilarious).
One time I sneak up on the new foreman (I had worked with him on days and he was cool…), slid the blade of my utility knife into the center loop in the back…and he reached back to grab my hand, getting a handful of razor sharp knife.
He was off work for 3 weeks. I felt like a jack-ass. The game ended.
Plenty more where that came from…
I rarely laugh out loud at my desk, but there’s something hysterical about electricity and hair…thanks, Miller and LifeOnWry 
:D!!!
So there I was at work, stomping around the pantry behind the kitchen, trying to straighten the place up, and mumbling about the slobs I worked with.
There were three open mostly-empty gallon jugs of white vinegar sitting around… idiots. As I whipped the caps off to pour them together, I noticed… christ there’s another one!
I started to pour that one in, too, but stopped suspiciously. There was no label on that jug. Of course it had to be vinegar, but I thought I’d better make sure. So I put my nose to the spout and took a big sniff…
And after I’d recovered from bouncing off the wall and put my eyeballs back in place, I noted that no, it wasn’t vinegar but ammonia.
Just now I burnt the bottom of my feet walking on hot asphalt. I stepped out onto the driveway to go to the mailbox and thought “ooooh, that’s really hot!!!” An intelligent person might have gone back in to get shoes or socks or something, but I walked the quarter-mile down the driveway, going “oooh! ooooh! ouch!” all the way to the mailbox, and “OH SWEET JESUS IT BURNS!” all the way back. I’m just waiting for the blisters to form now… 
Lemme see if I can 'splain this one: I had an old light fixture above my bathroom sink in my old apartment. It was basically a light bulb, but it also had an electrical outlet in the base. But the base was only as wide as the bottom of the lightbulb, or only slightly wider than the width of the outlet. And you had to reach up to plug in the hair drying or curling iron or whatever.
Okay. Looking at the outlet, you have a left slot and a right slot. Lining up the appliance, you have a left prong (to go in the left slot) andd a right prong (to go in the right slot). So I plug in my hair dryer one day and it doesn’t turn on. I look up and the plug looks off-center to the base. So it occurs to me – and it did occur to me what was wrong, I want to emphasize that I was smart enough for that, if apparently just barely – that I have stuck the right prong into the left slot, and the left prong is simply out in the air, to the left of the base.
So to check if that’s the case, I reach up and grab the left prong.
Bzzzzzzt!
I did one of those full-body wooga wooga woogas, followed by hopping around the bathroom shaking my hand out. My hand tingled for the rest of the day, and I spent a lot of time wondering if there was any limit at all to how stupid I can be. (Probable answer: No.)
