I know there are loads of crazy people in San Francisco, but this takes the cake! I feel sorry for this guy because he is just either flat-out crazy or so tweaked out on methamphetamine or some other stimulant. He is doing handstands, grabbing people an at times acting like a crazy ninja.
WARNING: There are two videos here and both show full male nakedness. The first video appears to be taken by a BART employee. The second shows San Francisco Police arresting this person.
