South Park S22 E06 Time to Get Cereal

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

As it turns out, everyone should have taken Al Gore Cereal. The citizens of South Park have no idea the danger they're in. When dead citizens start popping up all over town, the boys realize they need Al Gore's help. The boys are willing to do almost anything to save the town, and themselves, but it may be just too late.
