"Why Does It Hurt When I Pee?" is the seventh track on Joe's Garage, Frank Zappa's triple concept album set in an America where music has been made totally illegal. It was typical of both Zappa's twisted sense of humour and his disdain for musical or any convention that he would give a song with this sort of toilet humour title and subject matter the grandiose treatment.

The reason it hurts is because Joe has contracted an unmentionable disease from Lucille (who features in the next song) not for the reason he thinks, or gives, here. The vocals are supplied by Ike Willis, a long term member of Zappa's entourage who shared his sense of humour.
"Why Does It Hurt When I Pee?" runs to 2 minutes 36 seconds. >>
