Aura popularis

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:
- For the 1st and 2nd guys, they shout: "There's a tsunami!"
- For the 3rd guy they shout: "That's the guy!"
- Nothing for the 4th guy
- Last scene: "Watch out!"
