Great list Rog...and great additions.

Yet one of (in my opinnion) the biggest assholes has not been mentioned;
Gunnery Sergant Hartman from Full Metal Jacket.
Man that guy was an epipeth of asshole-ism.
Who can forget lines like:

"Are you quitting on me? Well, are you? Then quit, you slimy fucking walrus-looking piece of shit! Get the fuck off of my obstacle! Get the fuck down off of my obstacle! NOW! MOVE IT! I'm going to rip your balls off, so you cannot contaminate the rest of the world! I will motivate you, Private Pyle, IF IT SHORT-DICKS EVERY CANNIBAL ON THE CONGO!"

AND

Gunnery Sergeant Hartman: How tall are you, private?
Private Cowboy: Sir, five-foot-nine, sir.
Gunnery Sergeant Hartman: Five-foot-nine, I didn't know they stacked shit that high.
