lmao, I don't know how many times I've watched that scene. *ding*
I smile every time I think of it now. Its simple but amazingly tense, its the kind of thing that Hitchcock could have done. At first I did wonder why they hired Mark Margolis (from Oz and tons of movies, you probably all recognize him from something) to just sit there and do nothing, but when he started doing his thing...ha!
