He is no shrinking violet - but FAI CEO John Delaney's suit may have to be sent to the cleaners after this impressive ice bucket challenge.
The football boss accepted the nod from comedian Mario Rosenstock for the charity challenge in aid of the Irish Motor Neurone Disease Association (IMNDA).
In a video of the event, Mr Delaney didn't change out of his corporate uniform - a navy suit and his traditional green tie - before being soaked.
"I was nominated by Mario Rosenstock pretending to be Roy Keane, but I'm sure Roy would love this as well so if you're watching, Roy, this is for you - just joking," he said.
To a round of applause, three employees threw a large bucket of water over 46-year-old, who later joked that they were all "sacked".
He did the challenge at FAI headquarters in Abbottstown and chose to nominate GAA Director-General Paraic Duffy and journalist Barry Egan.
The challenge has seen hundreds of thousands of people around the globe drench themselves with ice cold water with participants posting the film on social media and nominating others to follow suit.
The craze has already raised more than €350,000 for the IMNDA, with donations rising by the hour.
The phenomenon began in America last month and has raised millions of dollars for Amyotrophic Lateral Sclerosis (ALS), the US term for motor neurone disease.
Other famous faces that have been soaked over the weekend include Sky Sports presenter Rachel Wyse, who threw a bucket of water over herself on Sunday at Hill 16 in Croke Park.
Ireland rugby star Dave Kearney also completed the challenge on Sunday.
But he was outshone by his Leinster and Ireland teammate Cian Healy, who received a drenching with a fire hose.
