They say there’s a fine line between genius and stupidity. Alain Roberts certainly tests that theory as he scales the world’s tallest buildings.

Climbing tall structures is nothing new, but Alain tempts fate more than most. He does it all with no harnesses or safety equipment of any kind, so at any moment he could plunge to his death. And when you’re climbing so high, the likelihood of meeting such a grisly fate increases.

But it doesn’t seem to faze this human spiderman, who has traveled all over the world scaling tall buildings illegally. Recently he was nabbed climbing the 41-storey Royal Bank of Scotland building in Sydney, Australia.

The $750 fine seems nothing compared to that sort of adrenalin rush!
