Quote from Andy in Mafia
Michael Scott: What? What are you wearing? Who's Pat? Andy: If I'm gonna back you up, I need a weapon without drawing suspicion. And I have to justify it somehow, so I'm a mechanic with a tire thing. Dwight K. Schrute: Do you know how to use it? Andy: To change tires? No. But it's metal. I could hit somebody with it.
