M*A*S*H

Heal Thyself (8x17)

Air date: Jan 14, 1980

Colonel Potter turns crotchety when he catches the mumps, and his condition is worsened when Winchester gets the same disease and has to be quarantined with him. A temporary replacement surgeon, Newsome, is quickly brought into the 4077th and seems to be a gem in terms of both personality and ability.
