Megas XLR episode Universal Remote, Coop defeats Skalgar but in his monumental incompetence, manages to trash a whole city just to get back his remote control. Such comedy I love in cartoons.
That episode is so great. I especially like that the villain, Skalgar, is just "what if Unicron was puny?". I also love DBZ explosions gags and Goat still being stuck in the trunk by the end of the episode
