A cop was walking down the street, and in front of a theater he came across a strange scene. A tuxedo-clad man was repeatedly kicking another man who was down on the sidewalk.
“‘Ere ‘ere, wot’s all this?” the cop said, or words to that effect.
Tux: Well, see, officer, I’m a violinist.

Cop: So?

Tux: It’s like this– during a break, he came down from the audience and detuned one of my strings!

Cop: That’s all very well, but I don’t see why that entitles you to bekicking this poor gentleman.

Tux, Well, you see officer, he won’t tell me which string!
