David Walliams Swimming With Sharks

Friday 7th March

On Thursday, Heart Breakfast spoke to James Cracknell during his challenge to get from London to Africa using his own power.

This morning, Jamie and Harriet spoke to his swimming partner David Walliams, ahead of their swim across the shark-invested waters in the Strait of Gibraltar.

And - at the docks, all greased-up and in tight trunks - the Little Britain star discussed why killer whales are so called. Because they kill people apparently!

Don't worry if you missed the call... you can hear the whole thing again right here.
