In 1995, Megan Mullally starred in a Broadway revival of "How to Succeed in Business Without Really Trying." That play was written by Abe Burrows, the father of series director James Burrows.

Steve Sandoval, who appeared as a janitor, is the show's stage manager.

In the episode, Mrs. Adler walks in singing "Good Morning, Good Morning." Bobbi Adler is played by Debbie Reynolds , who sang the same song in Singin' in the Rain in 1952.

The guy at the movie theater reminds Will that they met at Jon Kinnally's party. Jon Kinnally is a writer/producer on the series.

In the episode "Whose Mom Is It Anyway", Will, Grace, Grace's mother and a guy called Andy are having lunch in an Indian restaurant. Everything in the restaurant is classy, well laid out and expensive... except... the vases containing the flowers on each table, are actually old soup cans with the labels still attached.

In the scene where the they are having a tenants meeting, the woman on the sofa tells Will that someone "stole" her umbrella, she says it's similar to the one Tim Kaiser has, and Tim Kaiser happens to be the show producer's name.

Jack suggests that Karen could torture Lorraine, an Englishwoman, by "tying her down and forcing her to watch the American version of anything British." The episode aired on NBC shortly after NBC's "Coupling," based on a successful British show by the same title, was cancelled due to low ratings and critical condemnation. Not to worry, though; NBC is already adapting the BBC's "The Office."
