Never underestimate the power of a viral video.

On Friday, Sgt. Scott Moore, of the 3rd Battalion 2nd Marines in Musa Qala, Afghanistan, posted on YouTube an 18-second video in which he asked actress Mila Kunis if she would accompany him to the Marine Corp Ball taking place November 18 in North Carolina.

The video quickly circulated around the Internet, and, over the weekend, Kunis was asked about it as she promoted her upcoming film 'Friends with Benefits.'

That's when Justin Timberlake, Kunis' on-screen friend with benefit, jumped in and played wingman for Moore.

"Have you seen this? Have you heard about this? You need to do it for your country,” Timberlake told Kunis, in front of a reporter for Fox 411. “I’m going to work on this, man. This needs to go down.”

Kunis didn't appear to be aware of the video. But once it was explained to her, she happily agreed to be Moore's date.
Read on to see the video that snagged a regular guy an evening out with one of the most desirable women in the world.
