Sometimes some of these proposals can be a little..you know. I really like this one. It started simply enough as a request for Amy Frankel to listen to a song in the back of an open Honda CRV. As the car began to slowly take off, Bruno Mars' "Marry You" blasted through the headphones she wore.

What unfolded as the music played was an elaborate flash mob/live action lip-dub staged by boyfriend Isaac Lamb. See it after the jump.

More than 60 of Lamb's friends and family took to the street to dance the choreographed proposal in real time.

At the end of the four-plus minute song, Lamb parted the crowd, walked up to Frankel and got down on one knee. Watch it all in the video.
