What is your favourite Knock Knock joke
January 25, 2007 10:29pm CST
My five year old son has recently discovered knock knock jokes. The problem is he only knows a couple of them, and he says them all the time. Please let me know what your favourite knock knock joke is so I can teach my kid some new ones. I'll start: Knock knock? Who's there? Lettuce. Lettuce who? Lettuce in it's cold outside!!! That kind of an idea.
