S1·E74 Kick the Edo Illness Out!
Aired July 21, 1979
Synopsis
A mysterious illness (beriberi) becomes common and Yoshimune calls his doctor to find out what the cause is. His doctor says only his own special blend of medicine (very expensive) can cure it. Oshino, the female doctor with a fist, however, believes the solution is more simple (and involves punching people).
