Manly Wade Wellman's story "The Desrick on Yandro" has a memorable climax where his reoccurring protagonist John the Balladeer is unfortunate enough to witness a Hide-Behind (along with some other Fearsome Critters) claim their latest victim.

Maybe Coleman discusses this, but Shatner's biggest problem isn't that he's bad, it's that he's often a lazy actor. He's admitted it himself in recent decades, he just saw Trek as a gig to make some money, and often didn't make the same effort with the scripts the other members of the cast did, especially Nimoy.

Glad to hear this evidently ended better than Kitt William's Masquerade treasure-hunt.

One classic Far Side strip has a scientist coming to a bad end when he uses his time machine to take a large rectal thermometer back to the Age of Dinosaurs to conduct some tests...

She's no Lena the Hyena!

The antlered fellow is probably a Wendigo.

People in far-north California and/or eastern Oregon keep making similar pitches, wanting to create a right-leaning state called Jefferson.
