One little girl's impromptu dancing at a Brooklyn subway stop has become a viral sensation.

The YouTube video dated in November and posted this week shows a young girl in a pink coat dancing to a cover of the Grateful Dead's "Me and My Uncle," played by Coyote & Crow at the Bedford Avenue station in Williamsburg?.

The girl's dancing was infectious, causing other commuters to join in the fun, and providing commuters with a nice distraction while waiting for the L train.

The video has been viewed nearly 1.4 million times since it was published on Dec. 4.
