BERLIN, GERMANY - NOVEMBER 28: An participant dressed as Santa Claus attends a gathering of volunteer student Santas and angels on November 28, 2015 in Berlin, Germany. The Studentenwerk Berlin, a student organization at the city's technical university (Technische Universitaet Berlin), sends out between 400 and 500 students and alumni dressed as Santas every year to visit company parties in December and families on Christmas Eve. The students, who must complete the workshop, participate as a way to make a little money to help fund their studies. (Photo by Adam Berry/Getty Images)
