Adored by the Network: In the late 1990s and early 2000s, there was good reason that the USA Network was nicknamed "The Wings Network", and ReelzChannel is quickly taking the same title with their airings of the series in 2012.
Enforced Method Acting: Fictional example; Joe surprise kisses Helen during their elaborate act in "The Puppetmaster". It is strongly implied that both of them wanted to do so, as indicated by the exchange below.
Helen: The kiss sure took me by surprise though. Joe: We [already] talked about the kiss. Helen: No we didn't. Joe: I could swear we did. Helen: I think I would've remembered.
Fake Nationality: Tony Shalhoub, Lebanese by birth, played Italian cab driver Antonio Scarpacci.
Antonio's cousin Dominic was played by the not even remotely Italian Maurice Godin.
And the woman they fought over was played by Argentine model Fabiana Udenio.
Missing Episode: "There's Always Room for Cello", in which Roy's son comes out of the closet, was the third episode produced but was not broadcast until halfway through the second season. Homosexuality was still something of a taboo topic for a sitcom in 1990, and NBC had reservations about such a relatively new show tackling the issue.
The Other Darrin: In flashbacks, the Hackett parents were played by different actors than the ones who played them in the series proper.
Real-Life Relative: Tim Daly's sister Tyne appeared in an episode, as did the spouses of Daly, Tony Shalhoub, and Amy Yasbeck.
What Could Have Been: Crystal Bernard's character Helen Chappel was originally of Greek descent and played by Peri Gilpin (better known for playing Roz Doyle in Frasier). Since Bernard had a Southern accent, Helen was rewritten.
