[I like "No! Cows moo!" better, but it was Jet's joke]
Jet bought a book of knock knock jokes and he had me read him a bunch last night. It took a dozen or two for him to get the format, and it was an easy way to figure out what words were unfamiliar to him, as he'd stumble able on the pronounciation. But he loved 'em.
Thing is that I don't think he's getting the puns. He just thinks the last lines are absurd, so he just laughs at the absurity and like making his own absurd ones.
Ice water who?
Ice water fly with a fly swatter!
You mean you drowned the fly in ice water and the smashed it with the swatter???!!
