In this picture made available on Tuesday, April 17, 2012, the "Boeoegg" burns on the Sechselaeuten meadow in Zurich, Switzerland, on Monday, April 16, 2012. The Sechselaeuten (ringing of the six o'clock bells) is a traditional end of winter festival with a parade of guilds in historical uniforms on horseback and the burning of the Boeoegg, a symbolic snowman, at 6 pm. According to traditional superstition the faster the Boeoegg burns, the hotter the summer will be and this snowman looks quite hot. (AP Photo/Keystone, Steffen Schmidt)
