Brave Sir Robin ran away.
Bravely ran away, away!
When danger reared its ugly head,
He bravely turned his tail and fled.
Yes, brave Sir Robin turned about
And gallantly he chickened out.
Bravely taking to his feet
He beat a very brave retreat,
Bravest of the brave, Sir Robin!

People that love Monty Python suck at life.

[KOTLP]

[pookvis]

where is that rounders quote gimmick when you need it?

[Passaman]

My two most quotable are Napoleon Dynamite and Tommy Boy. Of course, a few years ago it was all about The Life of Brian.

[mbillie1]

in all seriousness, "casablanca" is probably up there with the most quoted movies of all time (or at least most famously quoted movies of all time)

"round up the usual suspects"
"play it, sam"
"here's lookin' at you, kid"
"we'll always have paris"
"i'm shocked, SHOCKED to see that..."
"i stick my neck out for nobody"
"of all the gin joints in all the towns in all the world, she walks into mine..."

etc

also a great movie, bogart is the quintessential cool guy
