Remember the old Jimmy Soul song "If Ya Wanna Be Happy"? You may be drawing a blank until you remember the lesson is how the way to happiness is for a man to marry an ugly woman.

"From my personal point of view, get an ugly girl to marry you" goes the catchy tune. How that song ever survived the ire of the feminists is beyond me.

But the opposite phenomenon has been looked at by researchers--attractive women who marry uglier (or at least, PLAINER) men.

It turns out there may be a scientific answer for why Catherine Zeta Jones is married to Michael Douglas!!

You see, men who see themselves as more attractive than their wives tend to have (according to the study from the University of Tennessee) more disgruntled and negative feelings about marriage.

Theses men tended to offer "less emotional and practical support to their wives" according to Professor Jim McNulty.

So next time you see an attractive woman partnered up with an average or below-average looking guy, you might understand it better.

To quote the above referenced song: "Don't let your friends say you have no taste, Go ahead an marry anyway!"
