Horse Cock?
The answer was given on Page 1.
Was Ted Cassidy ever on Batman? I can vaguely remember B&R climbing a wall and Lurch sticking his head out a window to chat with them.
ETA: And since I’m guessing, Ted Gehring?
That’s your answer to everything.
Cassidy is on the list, but I don’t see Gehring.
Keep going…
Malachi Throne!
Good! 
Correction: **27 ** familiar actors guest starred on both ***TOS ***and Batman.
I’ll give you a clue: Not all of them had speaking roles.
What was the name of the government council of Phools?The Plenum Moronicum from Memoirs of a Space Traveler by Stanislaw Lem
… And one more brings the total to 28. If you can find more, my hat’s off to you.
Each points to the other. Simultaneously, they both say, “She is!”
And they do it adorably.
A very young Jane “Amanda” Wyatt was one of the inhabitants of Shangri-La. I mention Miramanee because, according to Memory Alpha, Kirk compares her village to Shangri-La in "The Paradise Syndrome’ and I didn’t want to sidetrack anyone.

H.G. Wells’ stories and Jules Verne’s don’t overlap all that much. Wells wrote about a Time Machine, Verne wrote 20,000 Leagues under the Sea. But there were two sets of novels in which each of them covered the same science fiction idea, in their very different ways. One was “The Trip to the Moon” – Jules Verne is From the Earth to the Moon (and its sequel, Around the Moon) and Wells in The First Men in the Moon.
What is the other science fiction trope they both wrote a novel about?
Hey, they offer me free beer, I’m there.
That was…interesting to see…but overall pretty awful.
Genius take on Verne vs. Wells (bonus! It’s a comic!):
