David John "Dave" Matthews (born January 9, 1967) is a South African-born American singer-songwriter, musician and actor, known as the lead vocalist, songwriter, and guitarist for the Dave Matthews Band.

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.
