The three main male characters' names are Tom, Dick and Harry. "Tom, Dick and Harry" is a phrase used as a synonym for "everyone" or when referring to "a set of nobodies; a persons of no note" (from "Brewer's Dictionary of Phrase and Fable"). "Tom, Dick or Harry" is no specific person but could be any random person.
In the episode where they go to New York to start a different life, Harry gets a job as the President of NBC. As president he arranges a new schedule for the spoof of Will & Grace (1998). (Will & Grace (1998) is produced by NBC).
