Change Of Instrument

A drummer decides to change his instrument. After some thought, he
decides on the accordion. So he goes to the music store and says to the
owner, "I'd like to look at the accordions, please."

The owner gestures to a shelf in the corner and says, "all of our
accordions are over there."

After browsing, the drummer says, "I think I'd like the big red one in
the corner."

The store owner looks at him and says, "You're a drummer, aren't you?"

The drummer, crestfallen, says, "How did you know?"

The store owner says, "That 'big red accordion' is the radiator."
