This is a clip from 'Troop of One Hundred', taken from a Japanese comedy/prank show, where a 100 people chase after random strangers and you see their reactions. Totally harmless but their reactions are priceless.
There was similar and very funny video... but I haven't been able to find it again... so if anybody knows what I am talking about, please, please share the link. =)
There is an alley with a guy doing surveying at one end. He asks a passerby (the victim) to help him by carrying a big red flag to the other end of the alley. Then he disappears, and a mob carrying picket signs sneaks up behind the victim as he walks down the alley. At other end of the alley, a squad of police in full riot gear appear. The victim turns around, only to find himself suddenly trapped between riot police and an angry mob.
