I concur. "The Grave" is one of the best. There's a lot of them I don't like however. "Five Characters In Search of an Exit" is a bore. "The Living Doll" is one I usually switch off as well. Too many episodes with dolls and mannequins. What's the one with Barney Phillips with a third eye? That's a good one. "The Hitchhiker" and "A Stop at Willoughby" are also very good ones. What's the one with Jack Warden and the artificial woman (on the prison asteroid)? I've always liked that one.
Just an aside; there are several Twilight Zone episodes with a jukebox, but never has a pinball machine appeared.

Yes. One Step Beyond is much spookier than TZ, especially since they're often shown from a worn print. My favorite episodes are "The Reunion", "The Stonecutter", "The Villa", and "To Know The End".
That Gottlieb "Skill Pool" was in at least two episodes.

Saw an Alfred Hitchcock Hour episode recently with him in it.

He's one of those guys who's appeared on every major TV show from the '50s-'70s.

The very last TZ episode. There's an interesting back story to that episode as well. It's obvious that the young girl's voice is overdubbed; by none other than the famous voice actress, the late June Foray. She was best known for the voice of Rocket J. Squirrel from Rocky and Bullwinkle fame.

Yes, and she also starred in one of my favorite One Step Beyond episodes; "To Know the End".

"Danger...Will Robinson!"
