Kenan and Kel/Nightmare Fuel


 * The special Two Heads Are Better Than None movie. It was much darker than what is normally seen. Including actual murders.
 * Don't forget the severed heads in the basement!
 * It leads to dark humor and Kel talks to them before realizing they're dead.
 * And the dinner they had was implied to be a person since it was never specified what type meat it was.
