What is better than watching some good clean tennis? Watching Jimmy Fallon and Justin Timberlake doing the "Single Ladies" dance from the bleachers!

Yup! Sports buffs got a 15-second show of the comedic pair getting their Beyonce on from the stands while attending Roger Federer's Quarterfinals Match on Sept. 9. Jimmy Fallon and Justin Timberlake are always a riot together, so the U.S. Open would of course be no different.

The former SNL cast member and pop star sat in the Emirates Airline Suite before busting out their moves. The hilarious moment appeared to be brought on by an announcer seemingly introducing the duo and judging by the cheers from the crowd, the megatrons spotlighting the celebrity duo, which jolted Jimmy Fallon to kick things off. He first threw a mischievous glance at Justin Timberlake before getting to his feet and doing the signature Queen Bee hand wave. Justin then follows. He puts down his beverage and dives straight into the "Single Ladies" choreographer. The crowd begins to cheer and nearby on-lookers begin cracking up at the impromptu dance number. Even the announcers are floored. They are heard laughing and commenting on how neither celeb missed a beat. Queen B would be proud! In fact, Yonce if you need two more back-up dancers, found em!

The comedic antics between the two did not stop there. Justin Timberlake joined Jimmy Fallon to kick-off "The Tonight Show with Jimmy Fallon" the same day. The pair performed the 6th installment to their musical sketch, "History of Rap." The hip-hop number is comprised of Jimmy and Justin singing, beatboxing, and dancing to a medley of famed rap tracks. The sixth episode paid homage to classics and modern bangers including, Salt-N-Pepa's "Let's Talk About Sex," R. Kelly's "Ignition", Kendrick Lamar's "B***h Don't Kill My Vibe," Fetty Wap's "My Way," Will Smith's "Summertime, and Big Sean's "I Don't F**k With You." On the throws of the musical routine Jimmy pulls a hilarious bit with a play on "Straight Outta Compton" to boot.

There really is no telling what these boys will be up to next. Is it possible to get a "History of Beyonce" medley soon?
