R.O.C.K. in the U.S.A. (A Salute To 60's Rock)
performed by John Mellencamp

A married man is granted the opportunity to have an affair by his wife. Joined in the fun by his best pal, things get a little out of control when both wives start engaging in extramarital activities as well.

After Manjula gives birth to octuplets that were the result of fertility drugs, she and Apu unintentionally allow a zookeeper to exploit their babies in exchange for help after corporate sponsors abandon them for a mom that has given birth to nontuplets in Shelbyville. After a failed rescue attempt by Homer and Apu, the zoo keeper agrees to return the babies only if Butch Patrick and Homer ride a tricycle dressed as Eddie Munster on stage while attacked by cobras.
