Danish radio host Rune Hedeman had promised to complete three challenges if he got more than 5000 Facebook likes: To sing a birthday song for the Danish prime minister Helle Thorning, to have his eye pierced, and to complete a winter swim across a channel near the Danish Radio center. He received about 20,000 likes, which again resulted in him completing all three challenges in sequence this morning.
I recommend skipping the birthday song and the piercing, as incredibly enough the icy swim seems the least painful part of this challenge, at least for us spectators :-P
See DR.dk (swim from about 3:57)
(Oh and yes, see-through wet retro swimsuit hefty ass crack alert)
