My buddy tells me his friend, who sings in a punk rock/grunge band, really pisses off the bass player when he sneakily reaches over during a song, and gives one of the tuning pegs a good twist.
He says, when the bass player eventually
notices it, he gets even madder when he won't tell him which
peg he turned.
