Never has a man worn a more appropriate shirt.
I'd have loved to interview that innocent bystander, like how do you not point? You just saw a guy lick another guys head and walk off...your only reaction is confusion? You don't sell him out? Mr. Clean and his comical gold chain collection is going to smack you in the head, you might want to point him in the right direction.
PS: I really hope this becomes the next internet trend, planking, tebowing, drive by licking? The only question is if enough people know how to make a .Gif, because still photos just won't cut it. I personally have no idea. I mean I'm sure I could google it to figure it out, but that just seems like a lot of work for a prank I most certainly am not going to do myself. Licking a man's head? Blech.
