Right now I am watching the Loved One. I’ve seen it before but it so hilarious I need to see it again. Remember, Jonathan Winters is in it as the character of “The Blessed Reverend” and also as his disreputable twin brother who runs a pet funeral home.

Comedy of the sort you'd see in films with visual gags like The Naked Gun or Tex Avery cartoons.
