"Great news, Mr. Oscarson," the psychiatrist reported. "After eighteen months of therapy, I can pronounce you finally and completely cured of your kleptomania. You'll never be trapped by the desire to steal again." "Gee, that's great, Doc," the patient replied. "And just to prove it, I want you to stop by Sears on the way home and walk the length of the store. You'll see - you'll feel no temptation to shoplift whatsoever." "Oh, Doctor, whatever can I do to thank you?" "Well," suggested the psychiatrist, "if you DO have a relapse, I could use a new microwave."
