The guys you were referring to were the Plutonians, which are also great. My favorite line, coming from Oglethrope:
"Oh would you? Please save us? From all zee money?"
And one of my favorite Carl lines:
"Yeah, I saw this thing plugged into my house, and I saw your house was lit up like the freakin' sun. So I put two and two together and decided that...you're pissin' me off."
Good Mooninite quote:
Frylock: "Don't drape that towel on my computer!"
Err: "I'm gonna!"
Man, I could go on and on with this stuff.
