On Tuesday, the Indiana Pacers went up against the Miami Heat and won, but there was another victory at the Indianapolis arena. As part of a headphones giveaway, Pacers forward Danny Granger was given a challenge: sing a song with the jam-cans on and blaring, and if teammates George Hill and Paul George can name the tune, a dude in the crowd wins the product. The song: Jay Z's "Holy Grail" featuring Justin Timberlake.
As it turns out, a bearded Timberlake was in the audience, watching the whole thing go down. As Granger sung out of key and his buddies got into it, JT listened intently and then gave a standing ovation. Watch above for now. If that clip is pulled down, visit the Pacers' official site.
