We have to give this guy in Pittsburgh, Pennsylvania a big gold star for creativity. He put together a flash mob as a marriage proposal. The guy's fiancée is a fan of flash mob videos, so he decided to use theater majors from a university to create his own.

Check out the flash mob and her response after the jump.

The flash mob started with a lady dancing to the Black Eyed Peas song "Imma Be." Other dancers then joined her. Eventually, the dancers pulled the man out of the crowd and he proposed to the stunned girlfriend.
