Reminds me of a few things my friend told me he saw some of his friends do. And it always started with them saying, "watch this." The ones I recall involve police.
One was the two of them were walking along, they saw some police. His friend said, "watch this." to him. Then he did a doubletake and started to run away from the police. You can guess what they did.
Another was someone who got a jump suit that looked like the one some folks in the city jail wear. They were about to go into a convience store and saw it has some police in it. He put this on and told my friend, "Watch this." And walked into the store. Again you can guess the reaction.
