My kids LOVE telling jokes. In fact, we plan on getting Gibson a joke book for his birthday (shh!) because he just tells jokes all day long. He has a few good ones, and the others he makes up. And well, they pretty much never make sense. Maya has taken up the joke-telling as well. This was their interaction this morning:
M: Knock, knock.
G: Who's there?
G: Lemon who?
M: Aren't you glad I didn't say spit?!
Rolling laughter followed. At least they get each other's jokes. :)
