Chuck Donegan's page had the bit about the fear of Geoff getting hit. Geoff participated in that page -- perhaps the detail came from him. Chuck is still here to answer that, naturally.
Maxine Fabe's book says it was about logistics -- it was easier to set dozens of skits for one gender vs. both.
While any of this could be true, my hunch tells me they simply wanted female contestants only, and had lines ready for whoever asked them why. Sort of like the Double Dare producers when asked about "wasting" food (Marc Summers has suggested the "we only use stale-dated food" line was probably made up to get critics off their back.)
Pretty sure the 70s version moved to Burbank later in its run.

My brain is telling me it's The Burbank Studios -- i.e. today's Warner Brothers, and not NBC Burbank (which, ahem, is now called The Burbank Studios). Is that right?
