Ringo, You Twit!

A drummer, tired from being ridiculed by his peers, decides to learn how to play some "real" musical instruments. He goes to a music store, walks in, approaches the store clerk, and says "I'll take that red trumpet over there and that accordion."

The store clerk looks at him a bit funny, and replies "OK, you can have the fire extinguisher but the radiator's got to stay".
