Failing a calendar change in the next 90 years, September 17th, 2098 - the date shown at the beginning of the episode - does not fall on a Thursday (as the prop calendar indicates), but a Wednesday.
Host: For your approval a painting that has to do with time. Not the brief moments left to our culprits in the previous story. Their years of imprisonment were minute little fragments compared to the time we talk of in this picture. We talk centuries now and what happens when men of one century send back items quite unbidden to men of another. We call this painting, The Little Black Bag.
Dr. William Fall: Distinguished ladies and gentlemen, before I begin this demonstration I'd like to pose to you an academic question. If I were to take this scalpel, this knife, imbed it in my throat, and then cut to a depth of, perhaps, three centimeters, now what, in your professional estimation, would be my chances of surviving?
An earlier adaptation of the short story "Little Black Bag" appeared on the classic sci-fi anthology show Tales of Tomorrow.
This episode is based on the short story "The Little Black Bag" by C. M. Kornbluth. The story was first published in Astounding Science Fiction (July 1950).
