An ex-colleague recently contacted me about teaching an after-school English class for high school students going abroad. I doubted I would have the time to teach it, but agreed to talk to the school.
I arrived for the interview and was shown to the waiting room. Time was passing slowly, and I was bored. So I started fiddling with my key chain. This key chain has a cow on it, and when you squeeze it, it moos four times: "Moo-moo-moo-moo."
After a while, I even struck up a conversation with it. "So cow, how much longer do you think we'll have to wait?" I asked. I squeezed the cow and it answered, "Moo-moo-moo-moo." I see. "And how much money do you think they'll pay me?" I asked the little cow. And he answered, "Moo-moo-moo-" -- and in walked the director.
