This drummer is sick of everyone ribbing him about not being a real musician, so he goes to the music shop to buy a proper instrument. He says to the owner "I'd like to see some guitars, please". The owner says "you must be a drummer". The drummer says "How did you know that?". The owner says "This is a fish shop". The drummer wanders down the street and finally finds the music shop. He's in there for hours, overwhelmed by the choice, weighing up all the different options. After much thought, he musters up all of his courage and says to the owner "I'd like the big red trumpet and that accordion over there". The owner says "Well, you can have the fire extinguisher, but I can't sell you the radiator".
