When you become a prankster, it's in your job description that something will go wrong. This guy learned the hard way when he got knocked out for trying to kiss a very large man. It started off as a great way to get free kisses from girls, but he ended up kissing someone's fist. As you can see, he is a very happy man in the beginning. His little prank is going off without a hitch, but for some reason he thought it would be fun to kiss a man, and not just any man, the largest man he could find. The first guy he walks up to ends up breaking his jaw.

I'm not really sure what he was expecting to happen. Instead of it being a prank about getting kisses for Valentine's day, it ended up being a "you got knocked the **** out" video!
