Mark Dolan (The Richard Taylor Interviews) puts a team of comedians and performers to the ultimate challenge: he and his studio audience want to know just one thing - who has the biggest Balls of Steel?

His special guests are keen to prove themselves by performing death-defying stunts, holding their nerve during hidden camera set-ups or by being juvenile and stupid in the presence of celebrities.

But have they really got what it takes? Guest presenters include Alex Zane, Olivia Lee and New Zealand's number one stuntman Randy Campbell.
