I don't know what it is about riding in a car that brings out the Knock-Knock jokes in my children. But, Kirk has turned the tables on FRitW a couple of times lately and it sure adds spice to the same old jokes!
It goes something like this:
FRitW: Knock Knock
Kirk: Come on in!
FRitW: No, Kirk, KNOCK KNOCK
Kirk: I said "Come in!"
FRitW: No, Kirk, Who's there?
Kirk: I don't know who is there, but they're welcome to come in.
FRitW: (with a TEENSY bit of exasperation in his voice) Mom - Knock Knock!
It truly cracks me up! And if you have to listen to old jokes there is nothing better than a preschooler's delivery or a teenager's response!
