Based on that it's about a guy who parachutes into a mental hospital and goes to the salon there, but the hairdresser is a crazy chick with big basketball tits. Or at least that's what he imagines, because she evaporates anyway. He goes looking for her, but ends up fingering Leonardo Decaprio in the movies because Leo got drunk and couldn't tell what was going on. Then some strange bald guys talk to each other and another one has a shower. Leo keeps having visions of being fingered by a guy with a parachute, so he runs around looking for him with a rifle. They won't let him out of there though, so he cries a bit and hangs off a cliff. The end.
Is that how it goes in the book?
