The episodes title is a reference to "The Bob Newhart Show". The phrase "Hi Bob," became the source of a popular drinking game with college students during the run of the show. Whenever someone on the show says, "Bob," each player had to take a drink. If someone said "Hi, Bob," you had to guzzle your drink.
The NASA "Red Worm" logo on the uniforms of the astronauts has been slightly altered in this alternate universe just like the older "Meatball" logo. In this alternate universe logo, the A's have a horizontal line in them.
Just before the opening credits, this episode uses a freeze frame of Gordo further referencing '70 television style.
This episode takes place from November 8 to December 14, 1974.
