Has anyone explained what "unicorn" means in the context of this show? I have seen some discussion but not a real explanation.
All I know about unicorns is that only a virgin can catch one. Probably that is not what the show is about.
Dreyfus was mentioned on the Dick Van Dyke show, IIRC. Something like "But he's innocent." "So was Dreyfus." This was the 1960s. Apparently the writers expected that many viewers knew about the Dreyfus case.
