South Park S02 E04 Chickenlover

"Four boys. One f**ked-up town."

The Booktastic bus is in town and soon everyone finds out that Officer Barbrady can't read. He is whisked off to school with the boys so he can save his job. While he's there someone in South Park is having sex with the town's chickens and only Officer Barbrady with his new deputies Kenny, Kyle, Stan, and Cartman can stop them!
