Input: Question: How old was the series that Grampa and Jasper imitate? Passage:Additionally, Homer sings Billy Joel's 1983 song "Uptown Girl". After drinking the tainted juice, Grampa and Jasper sit on a bench, laughing like the title characters from the series Beavis and Butt-head, while Flanders hallucinates skeletons and dancing bears (images associated with the Grateful Dead), marching hammers (from Pink Floyd's 1982 film Pink Floyd—The Wall) and The Rolling Stones' lips and tongue logo. Mr. Burns' film is credited as "An Alan Smithee Film", a reference to the Alan Smithee pseudonym credit used by directors who wanted to be disassociated from a film on which they had lost creative control, to the detriment of the final product. When Barney drinks alcohol to prevent the bad effects from the tainted juice, a pink elephant comes to his rescue, referencing the scene in Dumbo where Dumbo and Timothy drink alcohol and see pink elephants. Seth and Munchie's dog is named Ginsberg, thought to be a reference to beat poet Allen Ginsberg. Homer putting the flowers in the policemen's rifles is a reference to the iconic October 22, 1967 Life magazine picture, "Flower Power" by Bernie Boston.
