A woman goes to the doctor. "Doctor," she says, "I'm worried about my husband. He's started doing this whole Dr. Jekyll/Mr. Hyde thing. I've tried talking to him about it, but he won't listen. When he's normal he denies there's a problem. When he's being 'Mr. Hyde'...well, you can imagine! There's just no talking to him at all!"

The Doctor tells her to calm down, "I've seen this a number of times and the treatment is pretty simple. He'll have to start masturbating regularly."

"Masturbating? But Doctor, what kind of answer it that? What does that answer have to do with my husband's problem?" the wife asked.

"Well you see," the Doctor replied, "in these cases I've found that usually the patient just isn't feeling himself!"
