Q: If you think your wife is keeping secret how do you get it out her?

A: Call your wife on the phone from an undisclosed location. Mimic her mother's voice and say:

"Oh, dear, I seem to be kidnapped. They say they will release me only when you reveal any secrets you have kept from that dear, dear husband of yours. These kidnappers are wicked, awful, dangerous men. You best do as they say and tell Mommy the secrets."

Note: This plan only works if your wife's mother is still alive. If your wife's mother is deceased, try slipping sodium pentothol into her morning vodka.
