Flash mob dance routines are one of the latest ways to express your self in a group setting. What looks like a spontaneous dance in a public place is actually set up in advance. But it does have its creative uses!

Take dancers Jamin Love and Valerie Albania. Dating and dancing for six years combined to bring a wedding proposal! Practicing after hours, Jamin waited until he and Valerie were in Downtown Disney when Jamin's arranged  flash mob started dancing to the Bruno Mars song Marry You.

Halfway through the song he proposed. Watch her reaction courtesy of Good Morning America.
