In popular culture

  • In the Robot Chicken skit "Laff-A-Munich" segment of the episode "Ban on the Fun", after getting tired of always losing (although the Really Rottens did manage to win in some episodes of the actual series), the Really Rottens take hostage the Yogi Yahooeys and murder them. However later, shortly after Dread Baron and Mumbly receive a call from Captain Caveman, a bomb goes off killing both of them.
