Take That Fresh Prince: Keegan & Phil Showcase Celebratory Tush Slap

This Presidents Cup has been a study in contrasting celebrations, with Tiger and Kuchar unveiling a fun, slightly dorky, but totally harmless way to celebrate the kajillion birdies they've been making at what I thought was a difficult golf course!

Not to be outdone, Phil Mickelson and Keegan Bradley have been lighting up Muirfield Village, prompting Keegan to bring back the old-reliable, utterly masculine thought slightly awkward, robust slap on the ass to celebrate a sporting accomplishment.

Luke Kerr-Dineen offers a GIF if you want to relive this retro-sportsman celebratory gesture.

Speaking of Mickelson, who may be nursing a sore left rear cheek tonight, Bob Harig pays tribute to someone in his 19th straight year competing for the USA in an annual team competition and playing as well as ever.

Mickelson improved his Presidents Cup record to 19-15-10 on Friday in the weather-delayed second session along with partner Keegan Bradley, posting a 4 and 3 victory against the International team of Jason Day and Graham DeLaet in foursomes. The U.S. win pushed Team USA to a 4½ to 3½ lead with four four-ball matches still to be completed Saturday morning.

The duo lost just three holes -- two coming after Mickelson and Bradley had forged a 6-up lead. They produced six birdies and an eagle through 15 holes -- which is pretty stout in the alternate shot format.

Not to be outdone by Keegan, this Golfweek gallery shows that Phil is on board with the slapfest too.

And how could I forget, but Bleacher Report has evidence that Phil started all of this slapping at the Ryder Cup in 2012.
