Devo is an American rock band formed in 1972. The classic line-up of the band includes Mark and Bob Mothersbaughs, Gerald and Bob Casales and Alan Myers.
Peter goes to the Quahog Civic Center to see Devo in "Herpe, the Love Sore", armed with a whip taken from Quagmire's mail and proceeds to crack it at other patrons during "Whip It". Peter takes their instructions to "whip it good" as criticism and insists he is doing the best that he can.
An uncredited archive recording of them performing "Whip It" was used for their vocal performance.
