Matt Pritchard and Michael ‘Pancho’ Locke on Dirty Sanchez (Picture: MTV)

There’s a heart-stopping moment from a 2004 episode of Dirty Sanchez that encapsulates the madness of one of the most anarchic shows ever made.

It saw Michael ‘Pancho’ Locke jump off a three-metre board into a swimming pool while wearing a full set of Marines-style combat equipment. Unable to rise to the surface, he remained submerged for more than 30 seconds, dragged down to the bottom by the heavy kit.
