Sergeant Emma is the twentieth episode of Season 3 of The Brady Bunch, and the 69th overall episode of the series. Written by Harry Winkler and directed by Jack Arnold, it first aired 11 February 1972 on ABC.
When Alice goes on vacation, Cousin Emma - a sergeant from the Women's Army Corps - fills in.
Alice is taking a week-long vacation, but has arranged for her efficient identical cousin Emma to take over her job during her absence. Emma is a twenty-year veteran, a Master Sergeant with the Women's Army Corps. Emma runs the household like it is the military, micromanaging the household and making them do daily calisthenics, with the kids being Army privates. She only will allow things that are up to regulation. Carol and Mike get off only marginally better as "officers". As such, the kids, in their words, would like an "honorable discharge" from Emma's army. When Mike and Carol approach Emma to commend her for teaching discipline to the kids, Emma decides that they too should join the sessions. Everyone can't wait until Alice returns from her vacation, but a "welcome home" party intended for Alice is misconstrued by Emma as the Bradys' show of appreciation.
