An acupuncturist agrees to waive his $5,000 fee if he can't cure Larry's back. Coincidentally, a down-on-his-luck writer asks Larry for a $5,000 loan, claiming he'll soon pay the loan off since his wealthy father is close to death. Later, at a not-so-surprise birthday party for the writer's wife, Larry manages to convince the father to cut his son out of his will, but the old man dies before the change is made. That doesn't mean Larry will get his $5,000 back, although he is forced to pay off his acupuncturist, even though his back isn't cured.
