Proposing via flash mob, as the guy in this video does, is a pretty big risk. If she says no, you've got to deal with humiliation on a pretty grand scale.  But if she says yes, you're a hero. 

Nam and Trang met on the UCLA campus. So for his grand proposal, Nam brought her back to the place where their relationship sparked for a special surprise flash-mob dance party.

"You're so cheesy," Trang tells him when he delivers a heartfelt pledge of love in front of God and a huge crowd of people.

Does she say "yes"?  Watch the video and find out.
