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!?
