This is a favorite activity in our home too. Now our 19 month old gets in on the action by repeating knock knock jokes with varying levels of success. I swear that I say "who's there" at least 100 times a day! Oh well . . . better laughing than crying!
Knock, Knock.
Who's There?
Boo
Boo who?
Don't cry, it is only a joke.
Knock, Knock.
Who's There?
Atch
Atch who?
Bless you!
Knock, Knock.
Who's There?
Tuba
Tuba who?
Tuba-toothpaste!
For slightly older kids:
What do you call a sick eagle? Ill-eagle!

Thanks, folks! Have a good night . . . Don't forget to tip your servers . . .
