Mine is still the first one I saw, where they introduced Ench-Man, and the 3 teachers all dressed up like Cat-women in order to be his sidekicks.
I also liked all the ones with Happiness-Bunny, except the last one where he met wh***y.
The only thing I've liked about the last batch of episodes Adult Swim showed was the fact that they admitted how unfunny it is now that Evan Dorkin and Sarah Dyer aren't on as Funimation's only married punch-up-writer-team anymore. The only reason I'm still watching is out of disbelief that Standards allows them to show "Mister Elephant". I mean, in "Pupin the Turd", he kept stretching it out!
That actually was a pretty funny ep too, because of the subtitles in the scene with all the different characters on the stepping stones: "We briefly considered changing all these to western letters, but just gave up. Seriously, see how they're obscured by the steam? No way in Hell! Just pretend that's a 'B'."
