Id second that Space Dandy choice, that was my favorite of the first season.

Hank had been training for years to finally get a chance to BE Batman, you have a point. I think the worst episode of the "season" was a B+ in my book, so not a ton of seperation… but it feels wrong to leave such a good year(short though it was) off the books.

And while im thinking about it…
Steven Universe: "Tiger Millionare"
Adventure Time: "Wake Up/Escape From The Citadel"

Pretty sure that season 5 should qualify, so what about…
Venture Brothers: "What Color is Your Cleansuit?"
