Not too long ago I introduced the kids to the wonders of the knock-knock joke, including the justifiably-praised "banana" gag.
So, my four year old daughter comes up to me the other day.
"Knock, knock," she says.
"Who's there?" I reply.
She turns around so I'm looking at her back, squats slightly, and produces a large wet, mouth fart.
She will probably outgrow this kind of humor at some point, but I have a sinking feeling that I will not.
Hey, if you have a good knock-knock joke, I'd love to hear it. I'm always looking for new material.
