Oktoberfest!

Raise your glasses, it's Oktoberfest!

Waitresses carry beer mugs during the opening ceremony in the "Hofbraeuzelt" beer tent of the 180th Bavarian "Oktoberfest" beer festival in Munich, southern Germany, Sept. 21, 2013.

The world's largest beer festival, to be held from Sept. 21 to Oct. 6, 2013, will attract more than 6 million guests from around the world.
