"Pax vobiscum," which Hitchcock signs off with at the end of the episode, is latin for "peace be with you."
Alfred Hitchcock: And he did, too. Naturally, Benny was properly punished as is always the case on this program. Next time, we shall be back again with more crime and punishment. Pax vobiscum.
Alfred Hitchcock: (the picture is upside down, so it appears that Alfred is standing on the ceiling) Good evening. This is Alfred Hitchcock speaking to you from the bottom of the world. I mention this so that if snow should appear on your screen, you won't waste time adjusting your set. (a dog with a barrel around its neck wanders onto the set) Ah, man's best friend…and a dog, too! Even though I have all the comforts of home, I'm afraid that it is time for our play, and I wouldn't want everyone watching this standing on his head. (snaps fingers and picture rights itself and the dog disappears) Well, we seem to have lost the dog, but it's nice to feel the blood rushing to my feet again. Ladies and gentlemen, here, proper side up is our story: "A Little Sleep."
