You're Joking!

Peanut: Mommy, I have a joke for you.
Me (all excited because neither of them have ever told a joke before): OK, what is it?
Peanut: Knock knock
Me: Who's there?
Peanut: Family
Me: Family who?
Peanut: My family is me, my brother, Mom, and you!
Then, he laughed like crazy. We couldn'þ help but laugh, too. Then, thinking he was actually funny...

Peanut: Mommy, I have another joke for you.
Me: all right.
Peanut: Knock knock.
Me: Who's there?
Peanut: Ben
Me: Ben who?
Peanut: Ben. I'm a boy.
He laughed hysterically again. So did we.
