A married couple was enjoying a dinner out when a statuesque blonde walked over to their table, exchanged warm greetings with the husband, and walked off.

"Who was that?" the wife demanded.

"If you must know," the husband replied, "that was my mistress."

"Your mistress? That's it! I want a divorce!" the wife fumed.

The husband looked her straight in the eye and said, "Are you sure you want to give up our big house in the suburbs, your Mercedes, your furs, your jewelry, and our vacation home in Mexico?"

For a long time they continued dining in silence. Finally, the woman nudged her husband and said, "Isn't that Marty over there? Who's he with?"

"That's HIS mistress," her husband replied.

"Oh," she said, taking a bite of dessert. "Ours is much cuter."
