Oh, not the only disadvantage: being that 5 of the machines
are running Python3, and 4 are running Python2, and one is
still stubbornly running Python1, and being that the owner
forgot to mark them, if we put the dress in the wrong
machine -- *BOOM* -- exceptions all over the floor. 

Can anyone think of a way to version-test these machines
without wasting a quarter, or requiring the services of a
clean-up crew?
