So this drummer gets tired of all the abuse he gets from other musicians and decides to take up a new instrument. He goes to the corner store, looks around a while and decides on one that looks good. He catches the attention of a salesclerk and asks, "could I try that accordian in the corner?" The salesman says "You know, you're the third drummer who's asked me that this week." The drummer is astounded. "How did you know I was a drummer?" The salesman replies, "For one thing, this is a hardware store, not a music store. And that's not an accordian, it's a radiator."
