This is in my honest opinion one of the greatest scenes ever in movie history, back when movies relied on actually good comedy and awesomeness. if you are eating while watching this video, you may choke to death, it is just that funny and awesome.

What is, in your opinion, the greatest movie scene of all time?

i cant help but think of the "English, Motherfucker" scene from Pulp Fiction
i wanna be creative with my answer but.. thats the answer

Edit: that slapping scene was fucked up

Almost any from Jaws.

" Gotta be Wild Things where Denise Richards and Neve Campbell get it on in the pool. "

The final duel from For a Few Dollars More.

When Jack Burton catches that knife and throws it into the forehead of that ghost Chinese dude, all done while wearing women's lipstick.

The Unusual Suspects, at the end when the detective realizes that Verbal Kint has been lying throughout the movie and it's actually he who masterminded everything.
