"Mr. Hankey, the Christmas Poo" (1997)
Does this walk the line of good taste? Oh yeah. It's "South Park." The kids bar Kyle from playing Christmas games because he's a Jew. And Kyle's mother doesn't want her Jewish son in a Nativity play. Poor Kyle suggests that everyone sing the scatological, and nondenominational "Mr. Hankey Song," but no one is interested. Ultimately, the town parents insist that the kids' pageant be stripped of religious symbolism. The result: an abominable Philip Glass minimalist production with the kids in leotards. If any show is going to nail Christmas and political correctness, you know it will be "South Park."
