One of only three episodes to feature the introductory line, "Submitted for your approval" during Rod Serling's opening narration, which is the phrase usually most associated with the show's monologues.
An early draft of the script featured an alternate closing shot: One of the "frozen" people, whom McNulty has just run past, turns to face the camera after McNulty vanishes around a corner. It's Potts, who smiles and winks at us...indicating that, as with the watch he gave McNulty, there's a lot more to him than meets the eye.
This story obviously drew inspiration from a book written by John D. MacDonald and published a year earlier, in 1962 - "The Girl, the Gold Watch, and Everything". Much later the book was made into The Girl, the Gold Watch & Everything (1980) which was surprisingly loyal to the book's plot and details, only removing a couple of less important characters and scenes.
The helicopter seen briefly is a Sikorsky H-19 (S-55) Chickasaw.
After being given the stopwatch and discovering its power, McNulty is back in the bar and bragging to disbelieving customers, "Last night, I was at the Polo Grounds. And right in the middle of Ron Hunt's slide into second base, I stopped the game. Yeah, I stopped the game. I left my seat, I ran down on the field, I grabbed second base, and I moved it ten feet. Then I went back up into the stands, sat down, and stared the game again. And Hunt, instead of being out by ten feet, was safe, and the Mets went on to win the game because Snider doubled him home."
This refers to the 1963 season (the same season during which this episode was filmed) because 1963 is the only season during which Duke Snider played for the Mets. There were, in fact, three games that year in which Snider doubled home Ron Hunt. However, only the game of May 3 was a night game - and the Mets lost (despite Snider's double and two home runs). And in none of these games did Hunt have to slide into second base: Twice, he was on first base when Snider doubled him in, and the other time, Hunt reached second base on a passed ball before Snider hit his double.
