Input: Question: Who is the oldest band that Eric listens to? Passage:Eric is a well-known fan of science fiction, such as  and especially Star Wars, in which he compares himself to Luke Skywalker. He is also known to have a large, beloved collection of G.I. Joe. He listens to artists such as Led Zeppelin, KISS, Aerosmith, Pink Floyd, Lynyrd Skynyrd, Deep Purple, Queen, Styx and Rush. He is also a Beatles fan and has been known to liken his group of friends to them, accusing Jackie of "breaking up the band" with her romantic entanglements with Kelso and Hyde (calling her Yoko, in reference to Yoko Ono). It is also hinted that he is both a Batman and Spider-Man fan, having Spider-Man bed sheets and a considerable number of comic books, most of them bearing the Marvel Comics logo with the titular character on the covers. When he fights a fan at the Packers game, he tells Red that he learned his moves from Spider-Man; coincidentally, Topher Grace starred as Eddie Brock, a character who obtains powers very similar to Spider-Man, thus transforming him into the monstrous Venom in Spider-Man 3 in 2007.
