Xavier de le Rue is a mad man. Not a raving lunatic, more of an eccentric, but you can be sure when he's older he'll start to look more and more like a cross between Back To The Future's Emmet Brown, Indiana Jones' dad and Caractacus Potts from Chitty Chitty Bang Bang. All great personalities, but all nuttier than squirrel poo after eating a Snickers.
Want proof? Just watch the above edit from the man himself rappelling down a rock face into a line. He says it looks scary, but his voice sounds like he doesn't really mean it. He's even got time for a cheeky selfie as he waits for his mate before tearing the face a new one. Balls the size of watermelons that one.
