which one is right

There is a man who has three girlfriends, but he does not know which one to marry. So he decides to give each one $5000 and see how each of them spends it. 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, a CD player, a television, and a stereo and gives them to the man. She says, “I bought these gifts for you with the money because 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, and decided to marry the one with the biggest breasts.
