The fourth episode of the science fiction sitcom Come Back, Mrs. Noah, created by the writing duo behind the perennial favorite Are You Being Served? and starring Mollie Sugden, is aired by the BBC. 
The occupants of the Britannia 7 space station receive sobering news from Earth: the space shuttle that has just arrived to rescue them can only take a finite number of people home. Immediately, the stranded Britannia 7 residents begin sizing up the greatest achievements of their lives, each trying to prove his or her worthiness to return to Earth intact. The competition heats up until Carstairs points out that there might be another way to return home, though it’s a very experimental procedure – one he thinks should be tested first on Mrs. Noah.
