How does Prince Harry celebrate a trek across the South Pole? By drinking Champagne, of course. Out of a prosthetic leg. According to ABC News, the royal participated as a team member on a Walking with the Wounded expedition, which benefits wounded military members. While marching for 13 days through arctic topography, Harry specialized in latrine building, as described by actor Dominic West, and keeping morale up with “filthy” jokes. The trip’s completion was commemorated with a two-day bender with a few Icelandic truck drivers and drinking bubbly from former soldier Duncan Slater’s favorite prosthetic leg. All in the name of charity, of course. [ABC News]
