Great show!
This couple goes into a crypt, and afterwards the custodian comes in and tells them that anyone who goes into the crypt gets killed by the dead man interred there, for violating the crypt (except for the custodian, who is tolerated because he maintains the crypt).
Then for the rest of the show the couple flees the dead man, until he finally gets them!
I like The Hall of Fantasy and will try to give that episode a listen this week...
