Madonna offers relationship tips for laughs

 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 her relationship advice on NBC's “Marriage Ref,” where she joined actor-comedians Larry David and Ricky Gervais as a guest panelist on Thursday's edition. The show invites its “experts” to help analyze real-life disputes between married couples, mostly for laughs. Host Tom Papa makes the final ruling. In one case, Mindy Goldman was offering sexual favors to husband Alan if he would clean up the messy basement. A good idea? Madonna cracked that “it's weird that she wants him to be clean so that they can be dirty.”
