Will & Grace

You can see that Debra Messing wears an engagement ring in a few scenes.

This is Joe's first appearance since the season 7 episode "Key Party".

Debbie Reynolds, Debra Messing, and Megan Mulally all share wedding anniversaries in the month of September, separate years, of course.

Previously, Debra Messing had starred in a show, Ned and Stacey, where she was part of a fake marriage.

Much like James' marriage to Grace, in real life Taye Diggs married actress Idina Menzel, who just happens to be Jewish and of different race than himself.

Jack's ring tone is his rendition of the 1979 hit "Ring My Bell" by Anita Ward.

We learn that James is a photographer and that his last name is Hanson.

This is Elliot's first appearance since the season 6 episode "I Never Cheered for my Father".

This episode marks Michael Angarano's (Elliot) final appearance on the show.

The kiss between Will & James is the first interracial same-sex kiss shown on network television.

The NBC and TV Guide synopsis for this episode had the gang traveling to Los Angeles so Jack could accept an award for "Jack Talk" -- Best Local Cable Gay Talk Show Host.

Joan Jaffrey Poust (the woman who thought Grace was comedienne Kathy Griffin) is series writer Tracy Poust's mother. She also appeared in the season 5 episode "Fagmalion Part Two: Attack of the Clones."

This is Vince's first appearance since the season 7 episode "Partners".

This is Rob's first appearance since the season 5 episode "Homojo".

We learn that Karen built this "forbidden room" when she thought she was pregnant in the season 1 episode "The Unsinkable Mommy Adler." However, it turned out to be a false alarm.

This is Margot's first appearance since the season 7 episode "Partners".

We all know it would have been impossible for Rosario to clean up the bathroom that quickly. What the crew did was build two bathroom sets. While the camera was on Rosario cleaning up, Eric, Debra, Sean and Megan scurried over to the other set before the cameras needed to capture them.

Will picks up Sam's daughter saying it's his favorite niece, Casey, but the actress is credited as "Courtney".

Will's oldest brother Sam, originally played by John Slattery, was last seen in the season one episodes "Big Brother is Coming (Parts 1 and 2)." In this episode, he was replaced by Steven Weber for the role of Sam.

This is Marilyn Truman's first appearance since the season 7 episode "From Queer to Eternity".
