Hold tight, Spin fans, as we're in for another video-drenched episode of this column. See below for the ultimate amuse-bouche, featuring the Williams sisters, Bryan brothers, and the greatest men's tennis player the globe has ever seen, among others. Let's get to it:

TANDEM TRICKS  Bob and Mike Bryan have a long history of winning, which means an equally elongated highlight reel of chest bumps, their signature move. Or, if you're the ATP World Tour narrator here, their "notorious calling card." Watch them explain the physical nature of the manuever, which they say has to start from three or four feet away from each other.

SERVICE  Serena and Venus Williams, Novak Djokovic, Fernando Verdasco, and more took part in a fundraising tennis hit for First Serve, a South Florida charity, ahead of their first matches at the Sony Open. A local TV affiliate's sports reporter—not a shabby player, at that—was on the scene.

ACCESS ALLOWED  The WTA Tour held its usual all-access hour ahead of the Miami tournament's first-round matches, and the hour-plus video reveals attributes of a few players. Among them: new No. 5-ranked Simona Halep's mathematical mind. See the full clip here:

HOLY TROIKA  Roger Federer recently revealed his personal top three shots of all time—his own, of course. To the surprise of no one, Andy Roddick (on an overhead smash) and Andre Agassi (a magnificent lob), respectively, find themselves on the losing end of his craft. (See exhibit A here, and Exhibit B to boot.) But it nearly goes without saying that Fed's tweener at the 2009 U.S. Open against Novak Djokovic, perhaps his best shot ever of its ilk, remains quite possibly his favorite professional stroke of beauty ever. Do you believe otherwise? Just check out his reaction to it:

What's your favorite Federer shot ever? And is the Bryans' chest bump the best signature celebratory move of all time? Sound off below.
