Oh I agree. This is my favorite scene of all time, and all of those things are what make it so amazing. All these years later and it still drives me wild.
I LOVE how nerdy Jay is! I actually find it sort of believable. Don't be too hard on me for saying that, but to put cheating in context, with hesitation, disbelief, and worry that her boyfriend will figure it out because she's getting so stretched out, I just loved it!
