A man walks into a jewelry store to buy his girlfriend an engagement ring. Looking behind the glass case, he comes across an exquisite band with a handsome-sized rock in its center.

“Excuse me sir,” the gentleman says to the salesman. “How much is this ring?”

“Ah, that's a beautiful piece,” the salesman replies. “It goes for $10,000.”

“My God!” the man exclaimed. “That's a lot of money!”

“Yes, but a diamond is forever.”

“Perhaps,” the gentleman replied, “but my marriage won't last that long!”
