The story of this episode is based on Eddie Anderson's first appearance on Jack's radio show in 1937. He played a porter on a train Jack was on. Jack liked his delivery and distinctive voice so much that he added the character of Rochester later in the season.
Jack tells Sarah that Rochester has been with him eighteen years.
(discovering Don dressed as a 12-year-old kid hiding in Benny's berth)
Rochester: Oh, Mr. Benny! Come now!
Jack: He's got a thyroid condition!
Don: You see, Daddy. I told you it wouldn't work.
(discussing Rochester's starting salary)
Jack: What do you think would be a fair salary?
Rochester: I ain't gonna get that, so let start somewhere else.
Jack: You see, we understand each other already.
The story of how Benny and Rochester met was used again on the episode of 1/28/1962 How Jack Met Rochester. The story was different on Benny's radio series; in the episode How Jack Found Rochester airing 3/11/1945, the two met when Rochester was a cab driver.
