This episode has Haley Joel Osment as a guest star. His sister, Emily Osment has appeared in ten other episodes of this show as Theresa, but not this episode.
Sandy lists famous gay/bisexual actors ranging from Rock Hudson to Raymond Burr to Anthony Perkins. But he also mentions Cary Grant, who was only rumored to be a homosexual (despite several marriages and a daughter), which was intentional since Grant is last on the list after a deliberate pause.
Last series appearance by Alan Arkin.
Lisa Edelstein and Allison Janney both appear in this episode although without sharing any scenes. They both also appeared in 5 episodes of the first season of The West Wing.
