Adam Sandler was on The Tonight Show last night to promote Pixels (that movie based on a clever YouTube video from 5 years ago). Which of course meant that he and Jimmy Fallon would spend a few minutes talking about SNL before launching into one of Fallon's bizarre celebrity guest gags. This time it was the Lip Flip.

What is the Lip Flip exactly? Well, basically it's a face swap of the mouth and the stuff of nightmares. 

Props to you if you made it all the way through the video without crying.
