4. Keith Richards
A couple of years ago, Keith Richards wanted nothing more than to see the Rolling Stones return to the road. Sure, the last tour nearly ended when he fell out a coconut tree in Fiji and cracked his head open, but the band is his life and they'd been gone for too many years. But then he released his memoir, Life, which contained countless jabs at Mick Jagger – the only man on the planet with the power to bring the Stones back to life. Mick was livid beyond belief (particularly over the line about his "tiny todger"), but Keith couldn't help himself. He's always spoken his mind and done exactly what he wanted, consequences be damned. Somehow or another, he always manages to get by. He got caught with heroin in the late 1970s, and his only punishment was doing a concert for the blind. As a character in Wayne's World 2 said, "Keith cannot be killed by conventional weapons."
