My 4 year old daughter learned knock-knock jokes about a year ago, a never-ending source of entertainment for her; she loves to make them up:
Bath me because it’s almost bed time!
And we both crack up whether it’s funny or not.
Today she told me a regular joke for the first time:
What do you call a sleeping gorilla?
I don’t know. What do you call a sleeping gorilla?
A sleeping gorilla!
“I joked ya, Dad!”, she says as we both start laughing.
