He was making a joke to Darcie about not wearing tight white trousers after 1982 as you have a visible Panty line, he was not "showing his bum" to Darcie, merely pointing out the line, it was Darcie who said "commando" and Richard said "commando at the BBC I dont think so" then Bruce got in his face with his "no one is laughing but you" sneer and sent him packing, I really think you lot sohuld listen and try to follow a programme before having a go at people, Richard was just making a little joke, it was Bruce who blew it out of proportion when it was nothing to do with him.
And it was not the noise level, we all heard the way he said it, nasty.
