Attention, British swimmers. . .

It's big news that a piranha was found in the Thames. Nobody's saying it now but a few years ago when the BBC did a special on dangerous animals, they found no credible documented cases of piranhas killing a human, provoked or not. Most of the people bitten were fishermen (that evil fish snapped at me before I could kill and eat it). According to the old BBC report, piranha's got their reputation after Teddy Roosevelt saw a school of them "strip a cow in minutes." The piranhas in question were trapped in a pool of water after a tributary of the Amazon dried up and were at the point of starvation. Not saying that they're great bath toys but try a little perspective.
