Flash Mob Of 100 - Funny

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.For a translation of what they're shouting (thanks Digg):- For the 1st and 2nd guys, they shout: "There's a tsunami!!" (tsunami da!)- For the 3rd guy they shout: "That's the guy!!" (koitsu da!)- Nothing for the 4th guy- Last scene: "Watch out!! (danger)" (abunai!)
