 When Alferd wakes up from the bizarre dream about Frenchy, he  screams "IKE!" for no apparent reason. Trey Parker (I) (qv) later  explained that this was an obscure reference to the film  _Legend of Alfred Packer, The (1980)_ (qv), which was the first  biopic about Packers life. In one scene, Packer also wakes from a  dream and screams the exact same words, yet it is never explained  why.
