A tourist in Australia's Northern Territory teasing a crocodile beside his boat annoyed the animal so much that it jumped out of the water at him. The man escaped. From The Telegraph:
"I began playing with it for a photo,'' Mr Mashiah said. "I was pointing at it when it suddenly jumped up at me - I didn't realise that crocs were so aggressive.''Link (Thanks, Paul Saffo!)
The "saltie" – which experts believe probably approached the boat in search of a free feed of fish – propelled itself out of the water with terrifying speed. After narrowly missing its prey, it smashed into the side of the small metal boat before plunging back into the water.
