Knock Knock... Go Wash Your Hands

While making dinner, Isaac came running into the kitchen declaring that he has a new joke.

"Knock Knock, who's there? Pick it." (Yes, he did all the lines... knock knock jokes aren't really fully understood)

"Pick it who?"

**he pulls his hand out of his rear (in his underwear) and sticks his pointer finger at me with a smile**

I guess my disgusted reaction wasn't what he was looking for since he was immediately sent to the bathroom to wash his hands without any sort of laugh or praise.

I seriously don't know where he gets this stuff. Luke nor I walk around the house with out hands in our pants or telling bad knock knock jokes. This kid... he's hilarious, but man... he's gross.
