National Dance Day is today: Learn the choreography

For one day only, an entire nation will demonstrate beautiful hip-hop unity.

Well, that's kind of the goal behind today's National Dance Day.

It's presented by the Dizzy Feet Foundation, a group that includes "So You Think You Can Dance" producer Nigel Lythgoe, director Adam Shankman, "Dancing with the Stars" judge Carrie Ann Inaba and actress Katie Holmes.

The organization was formed "to help underprivileged young people realize their dream of becoming professional dancers and to support, improve, and increase access to dance education in the United States," according to the Dizzy Feet Foundation's website.

Why do we need a National Dance Day? Because there's a national dance, of course.
