Alfred Matthew "Weird Al" Yankovic is an American musical comedian known for his humorous songs that make light of popular culture and often parody specific songs by contemporary musical acts; original songs that are style pastiches of the work of other acts; and polka medleys of several popular songs, featuring his favored instrument, the accordion.
He made his appearance as The Storekeeper (a.k.a. The Devil) in Adam Ruins Games.
