Crocodile Dundee had a preternatural ability to lull crocs to sleep by making a strange inverted "surf's up!" hand gesture and weird noises. You are not Crocodile Dundee. If you come across a croc on a golf course or in your backyard, you are likely to run. That's a bad idea. It's only likely to aggravate the beast. Not to mention, a crocodile can run as fast as a human [source: Hickman].
The best course of action is to back away slowly and try not to attract any attention, which -- as you can tell by now -- is the "go-to" strategy for dealing with dangerous animals. If that doesn't work, go for the eyes. In 2011, an Australian miner named Eddie Sigai successfully fought off an attacking crocodile after being dragged underwater by one of the razor-toothed beasts. How'd Eddie pull it off? By making like a professional wrestler and gouging the croc in the eyes. Experts say it's one of few viable options, crocodiles jaws are too strong to unclench -- especially if you're trying to do it with one arm -- and its skin is thick enough to fend off ward off punching and stabbing [sources: Hickman, BBC].
