A lot has gone down at this year's U.S. Open so far. We've seen countless upsets (bye, Rafa), broken records, and tender, sisterly moments, to start. But, nothing has been quite as amazing — or rather, amusing — as what happened during a changeover at one of the men's quarterfinal matches on Wednesday night. Fortunately for us, Justin Timberlake and Jimmy Fallon sat next to each other to watch the match between Roger Federer and Richard Gasquet (Federer won, in case you missed it and were wondering). And when Beyoncé's "Single Ladies" came on during a break, the duo did exactly what you'd expect them to do: Get up and dance. The result is pretty much the best thing you'll see all week. Commentator John McEnroe quipped, "These guys are on the money. They'd make a good doubles team." We've got to wonder if Peter Fleming would agree. Watch the clip below, and scroll down to compare their moves to Queen Bey herself.
And, the original. Still epic.
