The Gumby Women In "Monty Python's Flying Circus"
There were, in fact, Gumbies of the womanly sort. They appeared for a few brief seconds at the end of the show containing the chemist sketch (the one where they aren't
allowed to say 'semprini', or Series II, Episode 4: 'The Buzz Aldrin Show' for you technical types). The gumbies say (shriek pehaps?) the magna verba (great words) "And now for something completely different…", they change into female gumbies, and then back again saying "That was fun!"
They were real women; they were the extras from the series.
Many thank yous to the wacky people at montypython.net for supplying this info to me, and the troupe Monty Python, whose dry humor I alone understand in my house.
