David Walliams says he's sticking to comedy sketches for a while
David Walliams is one of our best loved comedians - and now he's become a champion swimmer too, one of the 50 fastest people to swim the Channel.
It was all in aid of BBC Sport Relief, as David explained when he came into the Breakfast studio on Thursday.
David has raised £540,000 for Sport Relief so far, but is hoping that more money will come through after the docmentary about his swim, on BBC One on Thursday evening.
He said that although the training had been hard work, it had been a good day over all.
As he swam, people following in boats were shouting out the amount of money he'd raised for Radio One - and this really did spur him on.
It also helped, psychologically not to think about the ending of the swim, but to think of other things - such as music.
The songs going round in David's head, were, apparently, from the Pet Shop Boys and Dancing Queen, by Abba.
And as for what's next? David's already been asked to climb Everest - but he says for now, he's sticking to comedy.
