A novelist goes to the doctor for a checkup.
Doctor: "Hey, can you give me the name of your agent?"
Doctor: "I've got a 6-month sabbatical coming up, and I've always wanted to publish a novel."
Novelist thinks for a moment.
Novelist: "OK, but can you do me a favor in return?"
Doctor: "What do you have in mind?"
Novelist: "As it happens, I've got a free 6 months coming up myself, and I've always wanted to do open-heart surgery. Could you set something up with the hospital for me?"
