CLOWN: Are these, I pray you, wind instruments?
MUSICIAN: Ay, marry, are they, sir.
CLOWN: O, thereby hangs a tail.
MUSICIAN: Whereby hangs a tale, sir?

– William Shakespeare

Othello, Act 3, Scene 1. The Clown provides comic relief in what is otherwise a very serious and tragic drama. During his banter with the musicians the Clown is talking about the wind instruments and makes a fart joke. Punning on tale (meaning story) and tail (meaning anus), he suggests that their music stinks and the instruments they play sound like they are producing flatulence.
