Who can forget the epic diner scene from the romantic comedy classic When Harry Met Sally when Meg Ryan...em, faked IT, moaning high-pitched screams of pleasure in front of gawking onlookers?  Here's what happens when the scene leapt off the big screen into the real Katz's Diner.


New York City stunt club Improv Everywhere recreated the timeless scene, enlisting a flash mob of 20 women to recreate the mocked climax.  It was staged all unbeknownst to the deli's staffers, whose expressions are priceless.
