  • @Hiyyee I agree with you!

  • You know. I think the shark is just annoyed at the constant annoying heartbeat. D:

  • Morgan Freeman narrator voice:

    "The shark seems more interested in the faster heart beat, oh wait a minute...Yes, it seems the shark is coming in for a closer look! Yes, indeed the shark is interested *shark bumps the cage* My oh my, the shark bumped the cage! But the shark is retreating? It appears the man in the cage shit himself...Yes, it's confirmed, the man shit himself and the shark has lost all interest" ....0_0

  • Wait... how the hell did they get those shots of the guy from outside the cage?

  • It makes sense.. if the prey is nervous, they probably know they have something the predator wants..

  • God, seriously? How much money do they waste on this shit

  • @Cooiepwns

    Another good thing to do is to completely cover yourself in aluminum foil before entering the ocean.

    This will trick the shark into thinking you are a robot and attacks on robots make up less than 3% of all shark attacks.

  • @mbm13213 Well I think the sharks are to smart to attack by mistake. New research has found out, that human blood does not attract shark NEAR as much, as fish blood so that doesn't matter. 2 people thing is correct.

  • @MrAmerica1995 All aboard the Shit Train =w=

  • @unipangma trains are the shit
