My buddies and I are constantly quoting the "Vacation" movies. One of my friends gets a new shirt: "That's REAL nice, Clark!" Maybe your meal is very tasty: "I don't know why they call this stuff hamburger helper. It does just fine by itself!"

As you could imagine, our habit of doing this annoys the women in our group to no end.

But everybody has at least one movie they're constantly quoting...and some movies provide a seemingly endless supply of quotes. Here are nine of the best, along with a few classic quotes from each:

"Airplane"  (1980):  "I AM serious. And don't call me Shirley."  "Looks like I picked the wrong week to quit sniffing glue."

"Mean Girls"  (2004):  "Stop trying to make 'fetch' happen."  "Get in, loser. We're going shopping."

"Bill & Ted's Excellent Adventure"  (1989):  "Party on, dudes!"  "Be excellent to each other."

"Monty Python and the Holy Grail"  (1975):  "I fart in your general direction!"  "Bring out your dead!"

"Casablanca"  (1942):  "I think this is the beginning of a beautiful friendship."  "Here's looking at you, kid."

"Pulp Fiction"  (1994):  "I'm gonna get medieval on your a--."  "Bring out the gimp."

"The Princess Bride"  (1987):  "Hello. My name is Inigo Montoya. You killed my father. Prepare to die."  "Inconceivable!"

"The Big Lebowski"  (1998):  "(Eff) it dude, let's go bowling."  "You are entering a world of pain."

"This Is Spinal Tap"  (1984):  "These go to 11."  "Dozens of people spontaneously combust each year. It's just not really widely reported."

What other movies belong on this list?  Here are some that come to mind:  "Animal House", "Caddyshack", "Forrest Gump", "Anchorman", "Office Space", "A Christmas Story", "The Breakfast Club", "Napoleon Dynamite"...

"Scarface", "The Jerk", "Dumb & Dumber""Jerry Maguire", the "Godfather" movies, "The Hangover", "Rain Man", "Austin Powers"...dang, the options are pretty endless!
