Knock knock jokes? They sure try. But it's not the easiest thing in the world to come up with a knock knock joke. Anyway, M finally came up with one that actually works. Nathan about fell off his chair in astonishment.
Choo-choo there's a train coming through!
Bwahaha. Even good knock knock jokes aren't funny. E is hilarious. She just says "knock knock" over and over. Smiles and fake laughs.
