Comic Relief: BBC Wales' Jamie Owen's comedy turn
BBC Wales presenter Jamie Owen has turned stand-up comedian to raise funds for Comic Relief.
He had four weeks to train before performing a comedy routine in front of an audience at the BBC Club in Llandaff, Cardiff.
His act, one of many charity fundraisers planned for Red Nose Day, was broadcast live on the Radio Wales show he hosts with Louise Elliott.
The Wales Today anchor said the project had "caused my blood to run cold".
Regular listeners to Radio Wales' Jamie and Louise show had heard him being prepared for his task by stand-up tutor Logan Murray, who taught top Welsh comedian Rhod Gilbert.
Comedians Chris Corcoran and Milton Jones also passed on their advice on performance and material.
Before he took to the stage, Corcoran said: "Jamie is a funny bloke - his humour is very dry.
"My advice is to keep talking and something funny will happen, react in the moment and if you aren't a joke teller, don't tell jokes or you'll be appalling.
"And a word of warning about doing stand up. Often when people are asked their list of fears, stand up or public speaking often comes out at number one."
More than £1.5m was raised by Comic Relief in Wales last year, and more than 40 projects have received donations since then.
For one project in Rhyl, Denbighshire, the money raised by Comic Relief has meant young people have a safe haven to meet, play, and learn some crucial life skills.
The charity's £100,000 donation to the Rhyl Youth Action Group pays for a vital alcohol awareness programme in an area where underage drinking is an ongoing problem.
Other fundraising events scheduled around Wales include a sponsored head shave, a leg wax, a fancy dress parachute jump and an eight-day march along the 180-mile (289km) Offa's Dyke path from south to north Wales.
BBC One hosts a Red Nose Day programme from 1900 GMT on Friday.
