World number one golfer Rory McIlroy was drenched in ice cold water by Tiger Woods as both sportsmen took part in the charity challenge.
A number of celebrities worldwide have been joining the craze, which aims to raise money and awareness of ALS.
Both golfers were nominated and then picked their own victims, with McIlroy choosing former United States president George W Bush and Manchester United striker Wayne Rooney.
The duo completed the challenge after appearing on The Tonight Show in the US.
