Two American astronauts aboard the International Space Station shaved their heads after losing a World Cup bet. NASA astronauts Reid Wiseman and Steve Swanson made a wager with their German ISS crewmember Alexander Gerst on the United States-Germany World Cup Group H match. The German team beat the US, 1-0, which meant Wiseman and Swanson had to let Gerst shave their heads. -- Mornings @ ANC, June 30, 2014.
