Their Ryder Cup runneth over.

Victorious Team Europe’s boozefest on the 19th hole seemed to run over, too — until Monday morning.

Just ask Jamie Donaldson. The Welshman was candid about his state of mind — and a bit slow on the uptake — in an interview with Sky Sports.

Donaldson, a 38-year-old making his Ryder Cup debut, sealed the trophy defense for the Europeans with a brilliant wedge approach to clinch his Sunday singles match against Keegan Bradley. “I guess I just hit the shot of my life,” he exulted afterwards.

Then they started popping bottles, and world No. 1 Rory McIlroy wasn’t above some ejaculation humor.

Later, they broke into the wigs and kilts.
