Justin Timberlake's "Not a Bad Thing" is a great love song, which is why a New York man apparently used it to propose to his girlfriend this past January, on a Long Island Railroad train. In the new music video for the single, which premiered on Thursday's The Ellen DeGeneres Show, a documentary film crew is trying desperately to find that couple.

The video starts with a voiceover saying, "A young man proposed to his girlfriend playing a Justin Timberlake song. They were so in love. You almost never see that. We don't know who these people are or what their story is, but maybe you do...Have you seen this couple?"

The clip, which also features other couples talking about friendship, romance and love, then follows the documentary crew as they create "Have You Seen this Couple?" signs, ask random strangers and use the media to help them find the couple from the train.

Ultimately, the music video leaves viewers wondering if the documentary crew succeeds in finding the couple, since it ends with a "To Be Continued" message.

"Not a Bad Thing" is the third single from Justin's The 20/20 Experience -- 2 of 2.
