In this cute illustration, John Schwegel mixes Star Wars and Regular Show. Though not pictured, Benson would obviously be an ever-irritable Obi-Wan Kenobi and Muscle Man would be Lando Calrissian.
I've just learned that on Regular Show, Mark Hamill voices Skips the yeti (Chewbacca). That's all the more reason for a full-length crossover episode.
