David Lee Roth (born October 10, 1954) is an American rock vocalist, musician, songwriter, actor, author, and former radio personality, primarily known as the original and repeat lead singer of the band Van Halen, as well as a notable solo career.
In "Cop and a Half-Wit", Peter tells Joe he's in great shape since working out with his Dave Matthews punching bag. But when he decides it isn't annoying enough, he swaps it out for one of David Lee Roth.
After becoming hooked on Van Halen's 1984 in "Coma Guy", Peter dresses like David Lee Roth.
