Chariots of the Dogs is one of the strongest episodes of the entire series. The way that the designers have taken advantage of the time-traveling aspect to showcase the wacky and chaotic nature of the characters is just inspired. Great writing, great animation and great voice acting support it all the way through. The puzzles aren't just peripheral, throwaway problems designed only to extend the length of the game but are actually legitimate, meaningful parts of the story that provide a nice challenge that never distracts you from why you're trying to solve them. And T-H-E-Y are hilarious.
