Apparently, this man, who is said to have been high on PCP, attacked and assaulted several people while naked at a San Francisco subway station.  What would you have done?

Personally, I probably would've laughed until I realized he was serious. After that, I might've let him get close enough to "grab a handful" and squeeze as hard as I could with my left hand while issuing a right hook.

What would you have done?
