We All Scream for Ice Cream (S02E10)

William Forsythe stars as Buster The Clown, a mentally challenged man who sells ice cream his Cheery Tyme truck until a cruel prank by a bunch of neighborhood boys goes horrifically wrong. A generation later they're all grown men with families, but the crime of their past may now be trolling for their children: Buster and his truck have returned for sweet revenge, and every frozen treat will bring its own taste of Hell.
