What would you call it when a rational person ends up in a zany world. They react to it like any normal person would, as they are completely baffled by it. In the end, this world is just too much for them to handle, and they snap in the end. For example, in The Simpsons episode, "Homer's Enemy, where Frank Grimes, a rational man, ends up in Springfield, and cannot comprehend how Homer is able to swing through life with little effort, and has trouble comprehending the wackiness of Springfield. Another example would be in the SpongeBob SquarePants episode "SpongeBob Meets the Strangler where the titular Strangler poses as SpongeBob's bodyguard, but in the process, his stupidity becomes too much for the Strangler to handle, which ends up making him snap in the end.
