Here are 40+ knock, knock jokes that kids will be sure to love!

These jokes are clean and family friendly and will definitely get everyone laughing.

I think knock, knock jokes are a childhood rite of passage.  Yes, they’re corny and goofy, but kids LOVE them!  And then of course then they have to make up their own – which make absolutely no sense at all! 🙂

We love all kinds of jokes, so be sure to check out our hilarious jokes for kids. You’ll also want to print these funny lunchbox joke cards.

    Lol! Thanks!! Some I hadn't heard and some I'd forgotten. That Doctor Who one was around when I was a kid (and possibly when my dad was a kid) but he can still get credit since he hasn't heard. My kids enjoy that one. I add the oooeeeooo from the theme or try to make TARDIS noises after the punchline. Actually, the interrupting cow one... I started doing an interrupting Dalek, coming in with "EXTERMINATE" before they're done asking, "Interrupting Dalek who?"
