A woman who is getting married for the fourth time goes to a dressmaker to order a white wedding gown.
Dressmaker: Madam, I can't make you a white wedding gown! This is your fourth marriage!
Woman (sheepishly): No, it's OK, I still "qualify".
Dressmaker: How can that be?!
Woman: Well, my first husband was a gynecologist, and all he ever wanted to do was look at it.
My second husband was a psychologist, and all he ever wanted to do was talk about it.
My third husband was a stamp collector. God, I miss him!
