"Birthday" features a gathering of family and friends for Edina's fortieth birthday, but it seems Edina has gotten out of the wrong side of the bed! Saffy's guest list includes Justin, and his boyfriend, Oliver (played by Gary Beadle, who also played Oliver in the "Happy New Year" episode, and the special, "The Last Shout.") Edina's mother is also on hand for the birthday lunch and festivities. Patsy arrives by way of motorcycle. Edina's first ex-husband, Marshall, and his girlfriend Bo are on the guest list, and they are introduced in this episode. As usual, Serge is mentioned but absent for the birthday event. During the gathering it is learned that Marshall and Justin are both paying support on Edina's household. The ex-husbands decide to look into the matter, which is later solved in the "Poor" episode. One of Edina's birthday gifts is a karaoke entertainment system, which Edina and Patsy use to full advantage! They even sing the show's theme song!
