King of the Hill

Junie Harper, a conservative church member, declares that Halloween is a Satanic holiday, and gets the school to shut down Hank's "Haunted House" on the grounds that it violates the separation of church and state. Luanne and even Bobby start to believe Junie when she says that Hank is a Satanist, and Hank has to fight against Junie's attempt to cancel Halloween for the whole town.
