JERSEY CITY, N.J. — It ain’t over ‘til the fat lady sings. Or in this case, Jordan Spieth and Dustin Johnson show off their pipes.

On Sunday evening, Team USA had a predictably jovial press conference following its 19-11 thumping at the 2017 Presidents Cup. But no one could have seen this coming.

When the question of favorite song sung by the fans at Liberty National came up, it was Jordan Spieth who first burst into a rendition of “Si-Woo shakin’ that ass,” a play on International Team member Si-Woo Kim and Groove Armada’s 1999 track, “I see you baby (shakin’ that ass).” And Spieth really got into it:

Moments later, Dustin Johnson gave everyone in the room another (pleasant) surprise by jumping in with his own version:

And a declaration.

“Best song, ever,” the World No. 1 said. “Ever. By any side.”

That’s a pretty bold statement, DJ. But he seemed to be pretty serious about it. When the press conference ended, DJ momentarily climbed up on a table, sang it again, and this time, added an actual ass shake. This should be one heck of an after party. And no matter where it’s held, we’ve got a hunch about one song Team USA will request to hear.
