Reminds me of a Drew Carey episode where his brother sees someone he use to babysit and she asks him to do the funny thing he used to do. After some proding he finally agrees and starts blowing on her stomach. Just then his wife, Mimi walks up:
Steve: Oh hi honey! This is little Kellie Newmar, I used to babysit her. I was just doing something I used to do that made her laugh. Kellie: Actually Steve, I was talking about the church and the steeple trick. I never thought you would actually blow on my belly. Steve: Oh, that! Here is the church, here is the steeple... Mimi: Do that again and I'll break all your people!
