Here’s a few……so hard to chose just one……

Supersonic bionic robot voodoo power

looks like your veculuar .. is some what constricted

I believe it is Doctor Octagon who is responsible for “Half Shark Alligator Half Man,” perhaps the most brilliant hip hop song of all time. The title is the best lyric.

“Now my helmet’s on, you can’t tell me I’m not in space…. ”

from Earth People on the freaky Dr. Octagonecologyst album.

I’m gonna have to stick with 80s Kool Keith:
“Your head is triangle / Like a mango”

Although the spoken intro for Black Elvis is spectacular:
“Why are you smirking up your face, making obnoxious facial scenes like I supposed to be scared”

Best Kool Keith lyric – “Hold upright, I burn your anus with the purple light”.

“Change my pitch up, smack my bitch up” – Critical Beatdown

REALLY hate to say this, but “Dogs drink my piss” from sex style is stuck in my head fairly frequently. GD i hate admitting that.

“you say Shaq is your cousin, I don’t believe you”
