The self control that dude has must be amazing. Imagine all the drunk br0's that want to fight him just because he's some weirdo in a costume. The dude is trained in MMA and could most likely take out most of them, but instead just calls the cops and ignores them.

I dont think you can go wrong with any benchmade though
