The first one goes out and gets a total makeover with the money. She gets new clothes, a new hairdo, manicure, pedicure, the works, and tells the man, "I spent the money so I could look pretty for you because I love you so much."
The second one went out and bought new golf clubs, CD player, a television, and a stereo and gives them to the man. She says, "I bought these gifts for you with the money becuase I love you so much."
The third one takes the $5000 and invests it in the stock market, doubles her investment, returns the $5000 to the man and reinvests the rest. She says, "I am investing the rest of the money for our future because I love you so much."
The man thought long and hard about how each of the women spent the money. Then he married the one with the biggest tits.
