"I've good news for you," said the psychiatrist. "You're a
well man. It won't be necessary for you to continue the
analysis any longer."
"How wonderful, doctor," said the patient. "I'm so very
pleased, I wish there were something special I could do for
you in return."
"Oh, that's not necessary. You've paid your bill and that's
all that's expected."
"But really, doctor, I'm so elated I could kiss you!"
"No, don't do that. Actually, we shouldn't even be lying here
on the couch together."
