For me it's easily Bill Murray...
"This is one time where television really fails to capture the true excitement of a large squirrel predicting the weather"
"I never liked a girl well enough to give her twelve sharp knives."
OK, but after dinner, don't put any of those old cheap moves on me. It's different now.
"Oh, no. I have all new cheap moves"
"Can I have another one of these with some booze in it?"
"You're on a gravy train with biscuit wheels."
"Now, for some of you it doesn't matter. You were born rich and you're going to stay rich. But here's my advice to the rest of you: Take dead aim on the rich boys. Get them in the crosshairs and take them down. Just remember, they can buy anything but they can't buy backbone. Don't let them forget it. Thank you."
"Nobody steps on a church in my town"
"You never say, "I'm gonna fight you, Steve". You just smile and act natural, and then you sucker-punch him."
"We're gonna need champagne for 250 people, and send the stuff that you send to me. Don't send the stuff that I send to other people."
"To kill, you must know your enemy, and in this case my enemy is a varmint. And a varmint will never quit - ever. They're like the Viet Cong - Varmint Cong."
"Chicks dig me, because I rarely wear underwear and when I do it's usually something unusual."
"All right! This chick is TOAST!"
"I make it a rule never to get involved with possessed people... Actually, it's more of a guideline than a rule."
"C'mon, it's Czechoslovakia. We zip in, we pick 'em up, we zip right out again. We're not going to Moscow. It's Czechoslovakia. It's like going into Wisconsin."
"Alright, I gotta hang up now, because I gotta go kill everybody."
"I was in the Virgin Islands once. I met a girl. We ate lobster, drank piña coladas. At sunset, we made love like sea otters. That was a pretty good day. Why couldn't I get that day over and over and over?"
"Yes, it's true. This man has no dick."
"You know I'm not big on apologizing. So I'll just skip it if it's all the same to you."
