Madonna offers relationship tips on 'Marriage Ref'

Madonna doesn't think a wife should withhold sex from a sloppy husband.

But she believes a wife should dispose of her late husband's prosthetic leg to spare the feelings of the wife's current mate.

This was some of Madonna's relationship advice on NBC's The Marriage Ref, where she joined actor-comedians Larry David and Ricky Gervais as a guest panelist on Thursday's edition.

The show invites its panel of "experts" to help analyse real-life disputes between married couples, mostly for laughs. Host Tom Papa, aka The Marriage Ref, makes the final call.

In one case, Mindy Goldman was offering sexual favours to Alan, her husband of 28 years, if he would clean up their messy basement.

A good idea? "I think it's weird that she wants him to be clean so that they can be dirty," cracked Madonna.

Gervais wondered, "Could they combine the sex with the housework?"

Then Susan and David Harper, married for three years, were seen in their house squabbling over possessions left over from their past relationships. Susan wanted her husband to get rid of the sofa where David and his ex-wife might have had hanky-panky, while David complained about Susan hanging on to the ashes and prosthetic leg of Don, her late husband.

Madonna's swift solution: "He gets rid of the couch, she gets rid of the leg."

"This is easily the most uncomfortable hour I've ever spent in my life," sighed Larry David in the midst of the debate.

"Why?" Madonna retorted. "Because you're sitting next to a woman who's standing up to you?"

The Marriage Ref, which premiered last week, has Jerry Seinfeld as a creator and producer.
