performed by Fozzie, the Mutations, and JapaneseWhatnots on episode 317. When Fozzie comes onstage dressed as a cowboy to sing the opening number, he finds himself on a Japanese-themed set, dodging swords wielded by the Mutations dressed as samurai. The number consequently turns from "Oklahoma" to "Yokohama."
performed by Forgetful Jones in a 1988 sketch. When Kermit tries to stage a production of Oklahoma!, Forgetful Jones can't remember the vowel sound at the beginning of the word and sings "Aklahoma," "Eeklahoma," and "Iklahoma" instead.
