Knock knock jokes for kids are my secret weapon for turning frowns upside down. I mean, show me a kid under 12 who doesn’t grin the moment you say “Knock knock” — apparently the two funniest words in the English language. I’ve used knock knock jokes to get us through long car rides, waiting for meals at a restaurant, and even getting flu shots at the paediatrician, because I’ll take uncontrollable, milk-coming-out-their-noses laughter over whining any day.

Though they’re not exactly sophisticated, knock knock jokes have been around forever. Some say they date all the way back to the middle ages, when castle guards would mess with visitors on the other side of the door. Others credit Shakespeare, who wrote some knock knocking into Macbeth. One thing’s for sure,  the knock knock jokes I loved as a kid are still funny today, especially to my children, who can’t seem to get enough. And here’s the secret to telling kids’ knock knock jokes: the worse they are, the more kids laugh.
