Patient: "Doc, I am very stressed out and I am not getting proper sleep at night."
Doctor: "I am giving you some medicines and sleeping pills."
Patient: "Is this going to help?"
Doctor: "Yes, just give it to your wife before going to bed."
Doctor: I am sorry I can't treat your ailment!
Patient: Why doctor? Is it that serious?
Doctor: No. Your ailment was not covered in my medical study book.
Patient, trembling in fear: Which book was that?
Doctor: How to become doctor in 30 days!
