Tiger Woods and Rory McIlroy are competitors and opponents on the golf course, but they seem pretty tight when they’re not on the links — at least for as long as they’re both wearing the Nike swoosh.

The duo teamed up for an appearance Monday night on “The Tonight Show Starring Jimmy Fallon,” but that wasn’t all they did together. Arguably the two best golfers in the last couple of decades also teamed up for, what else, the ALS Ice Bucket Challenge.

Dressed in their Nike duds, Tiger and Rory took turns dumping frigid water on each other’s heads and sharing a whole bunch of laughs in the process.

Not bad.

They also had some pretty lofty challenges, with Woods calling out Nike chairman Phil Knight and tennis superstar Rafael Nadal and McIlroy challenging former president George W. Bush, international soccer star Wayne Rooney and model/actress Meghan Markle.
