Longest full-body ice contact

Wim Hof, of the Netherlands, set a new Guinness record for the longest full-body ice contact, standing in a tube filled with ice cubes for 1 hour, 13 minutes and 48 seconds in 2008. He's since broken his own record three times, once in 2010 and twice in 2011, with it currently standing at 1 hour, 52 minutes and 42 seconds.

He claims to use a Tantric practice that allows him to control his body thermostat, and is also known for climbing to the top of Mount Kilimanjaro in shorts.

His nickname, of course, is Iceman.
