McIlroy took part in the ice bucket challenge alongside Tiger Woods.
To laughter from those watching, the pair threw the icy water over each other in turn and then made their own nominations.
Tiger challenged Nike co-founder Phil Knight and tennis star Rafael Nadal.
And Rory wanted George W Bush, Manchester United footballer Wayne Rooney, and Suits star Maghan Markle to get soaked for a good cause.
Mr Bush posted a video of himself responding, saying: "I do not think it's presidential for me to be splashed with ice water, so I'm simply going to write you a cheque ..."
But, while signing said cheque, his wife Laura drenched him and claimed: "That cheque is from me - I don't want to ruin my hairstyle."
The former president then went on to challenge his friend and predecessor Bill Clinton.
"Yesterday was Bill's birthday and my gift to Bill is a bucket of cold water," he added.
The ice bucket craze has been raising awareness and funds for charities, including neurodegenerative illness ALS in the US and Macmillan Cancer Support in the UK.
A host of celebrities have been involved, from Lady Gaga to David Beckham.
Co Down actor and Fifty Shades star Jamie Dornan has also had a go.
This Morning's Ruth Langsford was soaked by husband Eamonn Holmes and Rylan Clark, after being nominated by Good Morning Britain's Ben Shephard and Susanna Reid.
The Foo Fighters put a lot of thought into their challenge ...
... and the rockers passed on the baton to writer Stephen King.
