Quinn Martin's Tales of the Unexpected

 

1977 NBC. Anthology series. Saw this mentioned yesterday in the comments in an old post in the Kinja archive. Not to be confused with Roald Dahl's Tales of the Unexpected, which was a British show. Quite a few of the other Quinn Martin shows are already here. One or two of these is on Youtube. 8 episodes.
