OK parents I need your help:
I don’t have kids, so I don’t know what they find funny.
Here’s what I am looking for, if you could give me a joke that your kid thinks is funny.
Basically for lack of a better phrase, “A kid joke.”
I would be thinking of kids 5 and under. I am trying to figure out what the pre-1st grade and preschooler set thinks is funny.
I am looking for a verbal joke rather than those involving visual things.
In my experience as a kid, anything involving bodily functions is funny to 5 year olds.

What do you call a boomerang that doesn’t come back?

What’s a foot long and slippery?
A slipper- I love this joke, cause it’s ‘a foot long’, too.
“Mommy, Mommy, why do I keep running in circles?”
“Shut up or I will nail your other foot to the floor”
“Mommy, Johnny threw up”
“Why are you crying?”
“Cause he got all the big pieces”
There are a couple that I thought were beyond funny when I was 7.
why did the chicken cross the playground?
to get to the other slide.
IME 4yo is the earliest that kids really start to ‘get’ any jokes at all, and then only in the most rudimentary sense. You can tell most 4yo’s pretty much any string of gobbledygook, laugh at the end and they’ll probably laugh with you. Also, if you get a good joke, be prepared to hear it back every time you see the kid for the next year…
My 4yo knows exactly 2 jokes - “interrupting cow” (and variants - interrupting lion, interrupting starfish, interrupting dragon …) and “orange you glad I didn’t say banana”, and she tells them both with great gusto at every possible opportunity. But she gets the orange one wrong a lot, because she doesn’t really understand it, she just knows it’s “meant to be funny”
I keep trying to interest her in “what’s orange and sounds like a parrot” (A: ‘a carrot’), but so far no dice, it’s too complex for her.
Oh, and there’s also the joke our 10yo nephew made up.
Knock knock.
Who’s there?
Lemon pie.
Lemon pie who?
Lemon pie I want to be eaten!
(hey, you didn’t say grown ups had to find it funny!)
One muffin turns to the other, in the oven, and says “Man, it’s gettin’ hot in here!”
The other muffin looks back and says, “HOLY CRAP, a talking muffin!”
“Does your face hurt?”
My dad taught me that joke when I was about four or so. I loved telling it over and over and watching my dad’s reaction, but I didn’t really understand why it was funny or even that it was a joke.
If you don’t get it, you’re asking somebody if their face hurts. When they say no, you respond that (their face is so ugly that) it putting you in killing pain.
Why did the boy throw the butter out the window?
Because he wanted to see a butterfly.
My favorite joke in the world.
Why did the watermelon and honeydew have a large wedding?
A. Because they cantaloupe!
Har har har. Still one of my favorites.
I just told my (newly) 4 y.o. all of these jokes. The only one he thought funny was the interrupting cow one and now he’s repeating it over and over and over and over…
I agree with Aspidistra. I don’t think most kids really start thinking “funny” until they’re a little bit older. He makes up his own jokes that he things are hilarious, but they’re mostly just nonsense. He’s experimenting with the format of jokes (Knock knock, who’s there?, Blank!, Blank who?, Blanky blanko blink!), but hasn’t really gotten into wordplay, yet.
Q: What did the monster eat after the dentist fixed his toothache?
A: The dentist.
It’s not just kids who like that joke. I laughed too. The first couple of hundred times my son told it.
Ok, because I like ya, I’m now going to tell you my elephant jokes. I pull them out for my 15 nieces and nephews on request - they laugh when they are younger, they get them when they are slightly older, and then they correct me when I “tell them wrong” when they are older.
How do you shoot a blue elephant?
With a blue elephant gun!
How do you shoot a pink elephant?
To which they will probably answer: with a pink elephant gun?
And then you say, “No silly! the answer is:”
You hold their nose until they turn blue and then you shoot them with a blue elephant gun!
How do you know when an elephant has been in your refrigerator?
You see his footprints in the butter.
Why does the elephant wear green tennis shoes?
[spoiler] So he can hide on pool tables!
Then there’s the follow up question:
Q: Ever see an elephant hiding on a pool table? (No) See how well they hide!![/spoiler]
Why did the elephant wear red sneakers?
Because his green ones were in the wash!
I could go on - don’t want to bore you though . . .
I remember my daughter of about that age watching me eat a turkey sandwich and asking me “Do you love that turkey sandwich?”, and when I said “yes” she said “Well, why don’t you marry it then?”
I think she giggled hysterically for the next ten minutes.
This was my daughter’s favorite joke when she was 3:
What did the ghost give the monkey to eat?
Boo-nanas!
