Hundreds of people are dancing the night away, and it's all for a good cause.
It's the 13th annual "Greatest Fat Tuesday Party Ever" at the German House in Rochester.
The goal is to raise money for the March of Dimes Foundation, which provides life-saving research and programs for babies born too soon.
The party will carry on until midnight.
