Conversation between a cruise boat Captain and a NJ tourist lady.
Lady: "I understand you have a mink farm."
Captain: "Yup, I raise mink in the off season."
Lady: "Really? that's very interesting, I have a mink coat. Tell me, how often do you skin those mink"?
Captain: "More than once a year makes them nervous."

Marshall Dodge and I used to do this as part of a dialog in performances. Marshall Dodge is the "I" of Bert and I.
