My son has quickly learned that a sense of humor is a virtue. He probably thinks it's the most important of all of the virtues. Way more important than honesty or determination. Right? Anyway. Here's a sampling of his current shtick.
"Knock, knock?"
"Who's there?"
"Lettuce."
"Lettuce in, it's cold in here."
That joke is typically followed by this one.
"Knock, knock?"
"Who's there?"
"Apple vacuum."
"Apple vacuum who?"
"Apple vacuum in, it's cold in here"
And he likes to close with this one
"Knock, knock?"
"Who's there?"
"Lizard."
"Lizard in, it's cold in here"
Bah dum chhh!
