Remember that 'First Kiss' video where 'strangers' kissed each other but it was really a viral ad for some clothing company? Well screenwriter Max Landis decided to do his own parody version of it with 40 people he knew and got them to slap each other in the face.
Which shouldn't be enjoyable except it very much is AND OH MY GOD THAT'S HALEY JOEL OSMENT. As in the kid from The Sixth Sense:
Time is cruel.
Here's some behind-the-scenes action if you want to know how and why Landis put it all together. Or if you want to watch more people get slapped in the face.
