The part in the Matrix when Trinity says "Dodge this..."

The love medley in the elephant in Moulin Rouge

And the song in Billy Madison ("Do you have any more gum more gum more gum....")

Oh and let's not forget the dancing gopher in Caddyshack...tee hee!

I'm starting to be a dork and really like the "chick flicks" so far as those go I would have to say in the movie Ever After where Prince Henry comes to "rescue" Danielle and ask her to marry him and he kneels down and says:
I knee before you, not as a prince but as a man in love......"

Mallrats- "It's not a schooner, it's a SAILBOAT!"

The Big Lebowski- the Jesus..."Walter, what's a pederast? Shut the f up Donny, you're out of your element."

Amelie- the scene where Nino comes to her apartment and she kisses his face

Crual Intentions- the scene with the song "Colorblind"

Jurassic Park - when the team first catches a glimpse of the dinousars at the park and the theme song plays

Spirited Away - from the part where Chihiro goes to return something that belongs to the other witch til the end when she is reunited with her parents. I started crying when the dragon came knocking at the door...I forgot his name

Shawshank Redemption - the escape scene
Casablanca - the very last scene
Sound of Music - when all the children sing "So Long Farewell" to the part where even the adults say good nite and also the small dancing scene between Maria and Captain Von Trapp out on the patio

And also that scene from a movie I can't remember the name of. It's with Pierce Brosnan and Rene Russo and Brosnan plays an art thief. I loved the scene where he's doing his last gig in a museum where he's being set up and he manages to somehow fool the cameras

Godfather, where Al Pacino has all of the other heads of families killed off as he is annoited Godfather to his sister's child.

Great, great scene.

Though it's a cheesy film, in the Warriors the beach scene at the end "You warriors are good. Real good".
"The Best".

ETA: :( A year doing Film Studies and right now I can't think of anything other than Hollywood fare. Ah well maybe I'm tired. I'll look at the thread again sometime.

Another favorite--

the scene in Rudy when Sean Astin stands on the stool in the Notre Dame football locker room and acts out that famous speech.
