A bodhran owner, sick of all the drummer jokes, 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 our accordions are over there."

After a little while, the bodhran man says "I think I'd like the big red one in the corner."

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

The bodhran man, crestfallen, says, "How did you know?"

The store owner says "That big red one is the radiator."
