We've got a homemade puppet theatre set up in the living room. We're getting a lot of knock-knock jokes. (Mostly courtesy of the special feature on one of Signing Time's downloads, starring Lucy and Zack. The DVD is here.
Isabel's making up a lot of her own jokes, and laughing hysterically at them, and even James tells them. He does the rhythm and the tone just right, just--no words! I'll have to try to capture this on tape. :)
In case Mom and Dad are keeping track of the Curse of the Parent--"may your kids do to you what you did to me", I'm definitely getting payback for all my knock-knock jokes of yesteryear. (In case you didn't have the lucky experience of listening to these marvels of preschool humor, the punchline was always, inevitably, "a bottle-nose dolphin!")
