Very good, Doc. Here's an oldie modified slightly to fit your requirements.
Woman walks into a bridal shop and tells the clerk that she's having her fourth wedding and she wants to order a nice white gown. Clerk: "If you've already been married three times are you sure that you want a white gown?" Woman: "Certainly. I'm still a virgin". Clerk: "How can that be?". Woman: "Well, my first husband was a psychiatrist and all he wanted to do was talk about it. My second husband was a gynecologist and all he wanted to do was look at it. My third husband was a stamp collector and all he......boy, I sure miss that guy!"
(alternate punchline depending on what group of professionals you're speaking to) "But my next husband is a lawyer, so I'm sure that I'm going to get f***ed".
