Funnyman Frank Skinner is undergoing therapy in a bid to beat his fear of water.
The star is due to take part in a charity swimming challenge for Sport Relief, but the event has left him terrified as he is convinced he will inhale water.
The Room 101 host has enlisted the help of a shrink who is using an unusual Christmas-themed method to battle his phobia.
Speaking to The Sun, he said: "As well as going in the water I've been seeing a therapist about my fear of water - I think I'm going to breathe in water. He said 'Right, now sing that to the tune of Jingle Bells.'
Frank is due to undertake The Frank Skinner Dipping Challenge in March and will tackle his own Everest by swimming a length of an Olympic-sized swimming pool in front of an audience.
The comedian is being trained by four-time Olympic Karen Pickering, who will be assisted by another swimming teacher.
In a statement on her website, Karen said: "Getting him over his fear and then teaching him to swim are two massive hurdles. It sounds so silly when you look at people like David Walliams who swam the channel and Eddie Izzard, who ran 43 marathons in 51 days, but in a way, this is almost a bigger challenge."
