Pinkeye

Description

Kenny is killed by the Mir space station and becomes a zombie. This gets unnoticed as he is thought to have dressed up for Halloween, while those who get bitten and become zombies are diagnosed instead with pinkeye. Chef is the only one to realize the truth, and manages to tell Stan, Kyle, and Cartman about it just before getting bitten himself. The boys try to kill all the zombies until they realize they just have to kill the original zombie, Kenny, to get everybody back to normal. He is killed with a chainsaw, and when he appears to revive during his funeral, a statue falls onto him, followed by a jet crashing onto the statue.
