A wife is so frustrated with her lazy husband that she makes him to go a doctor to get a full check-up. The Doctor checks his blood, his reflexes, everything.
When it's all over the Doctor scratches his head, and tells the husband, "Frankly, I don't see anything wrong physically with you. As far as I can tell, you're just plain lazy."
To which the husband replies, "That's okay, Doc. But just give me a fancy medical term for it so I can get my wife off my back!"
