Best fake orgasm scene ever?

From When Harry Met Sally (1989). For those who haven't seen it, the story follows two friends, Harry (Billy Crystal) and Sally (Meg Ryan), over several years and various relationships. Harry claims that men and women can never be friends, while Meg argues that they can. To find out who is right, you'll have to see the movie. At one point Harry and Sally argue about fake orgasms, which leads to this:

This is a classic and funny part to a very good movie. The restaurant/deli scene where Sally fakes an orgasm to prove a point. "When Harry Met Sally" is a classic Billy Crystal & Meg Ryan flick...the woman who said that famous line is none other than TV's funny man actor/producer/director, (Rob Reiner)'s mom, Estelle, who passed away in 2008.

Any more nominees for the best or worst fake orgasm scene ever (excluding porn - that'd be too easy)?
