TV Producers have put Karma to the test by concocting this, frankly evil shark prank.

Brazilian hidden camera show Programa Silvio Santos thought it would be a great idea to make a large, fibre glass shark, sort of akin to Jaws, and scare the living shit out of several groups of bathers.

Although the fake shark clearly looks, well, a bit rubbish, the unsuspecting public must have been terrified as the blood soaked creation rose from the waves.
