Subbed in one band a few times where they put me front stage right for some reason (unusual spot for a bassist who doesn't sing). All night long idiots would repeatedly yell up to me, usually in the middle of a song, 'Hey, do ya'll know "Stairway to Heaven" (or "Proud Mary")?
Standard response: "Do I look like a farking Jukebox or DJ??'
They put you there because they were tired of answering the questions.
