Sorely annoyed when Charles (David Ogden Stiers) insists upon playing his French horn incessantly, Hawkeye (Alan Alda) and B.J. (Mike Farrell) issue an ultimatum: Either Charles ceases and desists, or they will refuse to take showers. Before long, the unbathed Hawk and Beej have become so intolerable that they have been "exiled" from the 4077th's mess hall--and practically everywhere else. Ultimately, the feud is settled with a torrent of cold water and a well-calculated "traffic accident", but not before Col. Potter (Harry Morgan) has tackled the more serious issue of a suicidal patient. With this episode, M*A*S*H settled into its fabled Monday-night timeslot, where it would play to spectacular ratings for the next five years.
