Simon Cowell double amuses judges
Britain's Got Talent judges are left in hysterics by the Chippendoubles - a dance act dressed up to resemble David Beckham, Gordon Ramsay, Daniel Craig - and Simon Cowell.
The fourth show in this series kicks off in London, where the Chippendoubles explain they are "a unique dance act and we all love to entertain".
Wearing masks and capes, the seven men perform to disco music in front of judges Cowell, Amanda Holden and Piers Morgan.
A Cowell lookalike is among the dancers - dressed in union flag boxer shorts - and the audience goes wild.
Meanwhile, university lecturer Hayashi, 36, hopes he can cut it with his blindfolded Samurai sword act, involving chopping up cucumbers attached to a helper's body.
"Simon is always saying he would like to see more dangerous stunts. What I'm about to do today is the most dangerous thing he will ever see," says Hayashi.
"There is a very real chance of my helper being injured or killed."
Co-host Ant asks the helper: "You're cool with that?" to which the helper nods nervously.
:: Britain's Got Talent airs tomorrow night on ITV1 at 8pm.
