I have to hand it to this guy...this is the ultimate way to propose to your girlfriend.

On Wednesday, Isaac Lamb of Portland, Oregon got a bunch of friends to help make a live lip-sync video to the song "Marry You" by Bruno Mars.

First his brother set it all up by having Isaac's girlfriend Amy sit on the back of an SUV with her legs hanging out.

He said he wanted to play a song for her. Then when the music started, the car slowly pulled out of the driveway and onto the street...and all of her friends showed up one at a time, and did a huge choreographed dance routine.
