Along with Lee Evans, Kevin Bishop and Shappi Khorsandi, they handed over £869,492 to staff and patients at London's Great Ormond Street Hospital.
The massive total was raised after more than 35 comedians and TV presenters took to the stage to perform at Channel 4's marathon Comedy Gala show at the O2.
Rob Brydon, Jonathan Ross, Katie Price and Alex Reid were also among those who took part in the comedy extravaganza.
The funnymen and women were laughing all the way to the bank, raising £669,492 in box office takings for charity plus £200,000 from Universal Pictures (UK) for advance sales of the forthcoming DVD release, available to buy from Monday.
The comedy extravaganza watched by 15,000 comedy fans at the O2 was so successful that plans are already under way for another one next year.
Alan, who opened the show on the night, said: "Wow! What a night! And what an amazing amount of money for Great Ormond Street - bring on next year!"
Michael added: "I'm absolutely thrilled that so much money has been raised for such a fantastic cause. This event will help so many children and I'm delighted to have taken part."
Channel 4's Comedy Gala at the O2 aired on Channel 4 on April 5 and was watched by three million viewers.
