I'm not sure if this is real or not, but if it is OMG! It's the thing nightmares are made of.

Just imagine jumping into the ocean and encountering a great white shark! That's exactly what happened to this guy in Sydney, Australia. A group of guys were filming themselves using GoPro cameras jumping off a ledge into the Sydney Harbor, then it happened. How do you not look appetizing and panicked while swimming for your life?

What starts off as fun and games quickly becomes a fight for survival. I can't even imagine what this guy was thinking or how terrified he must have been. As soon as he hits the water and surfaces his friends start yelling shark! Not being a great swimmer I bet I could set a world record as I made my way to shore.

There's a lot of debate as to whether it's real or fake. Hit play, watch it for yourself and decide.

If it's a fake, it's a good fake. Of course I wonder why all the screaming took place underwater, I mean sure I'd scream like a little girl too. But I'd be screaming underwater and on top as I swam my a-- off, not to mention all the vulgarity I'd be yelling.

Also, when someone yells shark don't you first wonder if they're joking? I've never lived near shark infested waters, but if someone yelled shark at me I'd think it was a joke. Maybe they don't joke about sharks in Australia, possibly because they really do have them.

Real or not it's a good video, I've watched it a few times and still can't make my mind up. One things for sure, if it's real this guy probably won't be jumping into the harbor any day soon. At least if he's got any sense. Shark week came early this year!
