You probably wouldn’t want to be at the receiving end of one, but pranks can be extremely amusing, especially if they mess with the heads of unsuspecting victims. And no one does it better than the Japanese.

This clip, titled “Troop of One Hundred,” comes from a Japanese TV show. The prank involves a hundred-strong mob chasing lone, innocent passers-by to see their responses. The reactions are hilarious and make you want to grab 100 people and try the same.

Of course, it doesn’t help the victims, when the people in the mob shout out things like “Here comes the tsunami!” “It’s that guy!” and “Danger!” in Japanese. Who wouldn’t be tempted to yelp and run for their lives in a situation like that?
