It suddenly occurred to me today that my kids finally know how to tell real jokes! "What does a pirate say in Alaska? Shiver me timbers, (laugh, laugh, laugh)." "What kind of bird can be heard at mealtime? a swallow, (ha ha ha)."
This is real progress! I don't know exactly when the change happened, but it hasn't been too long since they would say, "knock knock." "who's there?" "Meow" "meow who?" "Meow cat. (hysterical rolling on the floor)". I'm rolling my eyes. I know you can tell without me saying so.
So yippee for humor maturation!!
