After convincing a patient that the devil is not real, who should show up for a consult but Satan herself. It's just not as much fun anymore. Any suggestions?

SYNOPSIS:

A woman psychiatrist's patient, having undergone one exorcism, swears that the devil has returned. The psych convinces her that there is no such thing as the devil. It is a just a psychological manifestation of the patient's guilt. But once she leaves, an attractive woman named Lucy appears, claiming to be the devil. She seeks advice. Being the Lord of the Underworld just isn't any fun anymore. After some verbal jousting, the two make a bet: if the next patient will acknowledge Lucy's identity, the psych must take her to dinner and give her advice. Sure enough, the doctor loses and must take Lucy Ferr to a meal, where she gives the devil a present, guaranteed to increase both their practices.
