Spider-Pig is a song that Homer first sings when making Plopper walk on the ceiling like Spider-Man. This gag was added at the last minute. Film composer Hans Zimmer wrote a choral version of the song originally as a joke, but one of the producers heard it and asked him why it wasn't in the movie. It ended up accompanying Homer's epiphany trip and was the second song heard in the end credits. It is a parody of the Spider-Man theme song written by Bob Harris and Paul Francis Webster. The parody lyrics were written by James L. Brooks, Matt Groening, Al Jean, Ian Maxtone-Graham, George Meyer, David Mirkin, Mike Reiss, Mike Scully, Matt Selman, David Silverman, John Swartzwelder and Jon Vitti. The choral version appears on The Simpsons Movie: The Music album.
Homer's version
Spider-Pig, Spider-Pig,
Does whatever a Spider-Pig does.
Can he swing from a web?
No, he can't, he's a pig,
Look out, he is a Spider-Pig!
