[Airborne Butters]

Well, not as if I watch the series (look at name) but the goods one are

"Whateva" - Whateva, I do what I want! I run with 12 gangs.

"Big Firecracker" - The one where they make the worlds largest firework snake thing then it blows up over southpark and people are in black ashe, then chef comes back and goes "Hey everyone I'm back from Aruba!" "Howdy Chef, welcome back!" (Looks around see's everyone is in black ashe) "Ooooooook, everyone line up so I can whoooop all your asses"

"Fetal Babies"- Where Cartman sells a bunch of undead fetus's to a company but hagles for em like "O chuck, your breaking my balls here"

But Yeah, theres sooooooo many more
