You forgot sitting through poorly made Powerpoint Presentations.
Isn't that what started this line of suggestions, though?
ANYWAY, I forgot to mention:
MEGAS XLR -Pilot- Low Brow
So Felix Orion, who is a total bro, by the way, guys, sent me this little gem to watch, and watch I did. The pilot ran during the Cartoon Cartoon Summer, which, if I remember my childhood right, was a period in which many shorts were released and viewers voted to determine which ones got to be new Cartoon Cartoons. This is how Billy and Mandy and Sheep in the Big City happened, both of which were great shows until Billy stopped being important and Mandy became the invincible Mary Sue that alt-goth kids in Junior High and Hot Topic would worship forever (I might be slightly bitter about this).
Anyway, the short, which runs for like, seven and change minutes, is mostly the first episode of the show in a condensed format with lower-quality animation. Notably Kiva and Coop's eyes are more akin to Jaime's, and Kiva's face is really off model (her face wouldn't really get nailed down until the second season). The Glorft, and Gorath in particular, don't play much of a role in the short, but it is worth it to see the origins of Megas, the eightball Hadoken, and a number of series staple gags.
Basically it is a damn shame that there was never a third season of this show.
