Londoners shopping for fish got a fright today when a fake killer shark suddenly tried to bite them.
The prank, which was all caught on hidden cameras, is to celebrate Thursday night's premiere of SyFy's Sharknado 2: The Second One.
If you missed Sharknado the first time around, it's as simple as it sounds. Killer sharks get scooped up into a tornado, fly out and eat the first person they can get their teeth around. It stars Tara Reid and Ian Ziering, who in this second Sharknado instalment have to try and save New York from going under.
But before we get to all that, watch Londoners having a good old panic.
Well, apart from this lady, who is a total pro.
