Greenback: ...Everybody will be forced to visit my museum.
DM: Your museum?
Greenback: The Greenback Museum of Barry Manilow record sleeves!
DM: You fiend! You'll bring the world to its knees!
Penfold: It was a fish! Honest!
DM: (to crooks) You fiends! You've damaged his mind! (muttering) What there was of it.
Penfold: (off-camera) I HEARD THAT!!!
The sound of a train braking in this episode was used long before this episode as it was made for the Thomas the Tank Engine show.
The title of this episode is similiar to the film title Murder On The Orient Express.
