#1: "You Teutonic twat!" Harvey Korman had the greatest delivery of all time.

Runners up: John Candy, D Day Lewis (There will be blood), Malcom Mcdowell and of course, one of my all time favorite lines came from Groucho. "I can seen you in the kitchen. You're bending over the stove. I can't see the stove."

The Christmas Vacation rant has always been a favorite. Anything from A Fish Called Wanda is great, as is the Clockwork Orange one, if only because of the language--it's almost Shakespearean in tone. The Holy Grail quote is just classic. "You're a sad, strange little man and you have my pity" is awesome.

One of my favorites that wasn't on there (maybe because it's indirect):

Frenchie: What did she give him?
Marty: A lock of hair...from her chest!

They left out "Penisbreath" from of ET.

Best insult I've ever heard, though second-hand was delivered from a pissed off wife to her husband at a very important business dinner: "There's 500 miles of dick in this town, and I'm not taking any more shit from your 4 inches!"

I'll make it a tie between the Groucho line and "I fart in your general direction."

Two comebacks attributed to Winston Churchill.

Lady Astor: If you were my husband I would flavour your coffee with poison.
Churchill: Madam, if I were your husband, I should drink it.

Bessie Braddock: Winston, you're drunk!
Churchill: Bessie, you're ugly, and tomorrow morning I shall be sober.

There was only one bit from Peter Capaldi in the video above, but this man has raised swearing to rarified levels (the movie this comes from is pretty enjoyable, too):

I agree with Eric- D.D.L.'s line from There will Be Blood.

Second would be Cher's line from Witches of Eastwick.

All of that profanity just begs the question; how does the chihuahua survive after consuming the brain?

There were some good ones in that one.

But there were several more from Star Wars that could have fit in.

"You are a smelly pirate hooker" is one of my faves. But the whole list made me giggle.

I heard that R Lee Ermy was originally tapped to be a consultant on Full Metal Jacket but he decided he'd rather be the DI. After all, he was uniquely qualified, he was a USMC DI. His audition was a tape he made of himself spewing invectives and insults for a full fifteen minutes without repeating himself once.

I like to believe that story's true :)

Jack Lemmon in whatever movie that was("Glengarry Glen Ross"?). And the Jack Nicholson character in "As Good As It Gets" has good ones.

Important term, new to me:

"Fuckstart."

As in, "Time to fuckstart that woman..."
