Everyone has witnessed a flash mob on YouTube or in person, but I doubt anyone has seen something like this. Twenty women at Katz' Deli in New York City simultaneously improvised the Meg Ryan fake orgasm scene from 'When Harry Met Sally' and the results were - wow!

The stunt was part of Improv Everywhere's Movies in Real Life series.

Here is the scene from 'When Harry Met Sally' that these impressive women are reenacting. How was their performance? Did the video make you blush as much as it did us at the office?
