Goof: In the closing narrative, Hitchcock refers to Professor Mason as "Don," but throughout the show, he is called "Bob."
Alfred Hitchcock: Well, you can't win them all. I understand that Don Mason was condemned to a cell, very much like this one (gestures towards his surrounds). And now (Walks over to giant stacking blocks. Camera pans out and one can see that he is actually inside a playpen) Daddies and Mommies, I think the time has come to lam out of here. Suppose you take this opportunity to escape - until next time, of course (aims squirt gun at camera and fires water over lens).
Nancy: (getting ready to go to the gym) I've got to control my figure if I'm going to compete with all the jail bait in your classes.
Bob: That isn't very funny.
Bob: How'd you like to go for a drive? See a movie?
Nancy: Fine! When?
Bob: Now. Tonight.
Nancy: Well, what's come over you?
Bob: I don't know. I just felt like getting out. (gets defensive) Well, it's a perfectly normal, middle-class impulse! Is there anything wrong with that?
Nancy: No, but I've never known you to have impulses, middle-class or otherwise!
Alfred Hitchcock: (standing inside a jail cell, wearing striped prison coveralls) Good evening, fellow inmates. I suppose you're wondering why I'm here. I was picked by an agent from the Federal Bureau (looks puzzled)...the Bureau of Standards, that is. He claims I was lying about my weight. The vertical stripes were my tailor's idea. They not only give me that slim look, they also make it impossible for the guards to tell where the bars leave off and I begin. I have a different uniform for each day, and on each one, the stripes are closer together. In ten days, I expect to disappear completely. As for tonight's story, it is a somber little jig called "Silent Witness." It will occupy the space in just a moment.
