During "The Last Voyage of the Starship Enterprise" sketch, both Spock (Chevy Chase) and Kirk (John Belushi) say that NBC used to manufacture cookies. This is an esoteric reference to the earliest days of NBC. Before RCA launched the National Broadcasting Company in 1926, "NBC" was the trademarked nickname of the National Biscuit Company, the manufacturer of Oreo cookies and Ritz crackers. RCA bought the rights to the initials "NBC" and the National Biscuit Company adopted a new trademarked nickname - Nabisco.
The original live broadcast contained an accidental bit of brief nudity during the Weekend Update segment. Chevy Chase can be seen quickly covering a photo of a topless woman on the monitor behind him.
Elliott Gould's character in "The Last Voyage of the Starship Enterprise" sketch, programming executive Herb Goodman, was named after two NBC executives of the time, network president Herbert Schlosser and chairman of the board Julian Goodman. Goodman was president of NBC at the time Star Trek (1966) was cancelled in 1969.
Jane Curtin's character on Weekend Update is named after assistant to the producer Audrey Peart Dickman.
