Dude, you made my day! Before the "Dice Man" there was Rev Sam Kinison. Such a loss!
He taught me how to eat pussy before I even could pinky check or nose hit one. I gave a valiant effort in trying to find the monologue, but all I could find was THE SOURCE:
Oriental Lick Master
Not to forget about his bit on Necro's "There's a dick in my ass, OH OH OH!"
