Main Characters in this Episode
Frasier: Don't worry, Niles, no one takes him seriously.
Daphne: I never knew how many letters there were in the dolphin alphabet.
Carla: Back off, I'm toasting! The 20 years I have known you would have been less painful if I were covered with open sores and thrown into a pit with a bunch of diseased rats! But now, finally you're leaving! I know I am not as young as I used to be, but I can live again! I can live again! Finally, I can live!
Carla: Anyway, God bless.
Phil: I'm Phil. Al's been dead for fourteen years, ya dumb son of a bitch!
- Goof (factual errors): One of the well wishers who Cliff accidentally calls Al says that he has been dead for 14 years. Al Rosen, the man who played Al passed away in 1990, meaning that he had been dead for 12 years instead of 14.
- Goof (continuity error): Numerous times during Cliff's retirement party, his beer switches between having a rather large head of foam, and having no foam at all.
- This episode was part of NBC's 75th Anniversary celebration, in which actors from previous NBC shows guest starred in current ones.
- One of the guests at Cliff Clavin's retirement party appears to be director James Burrows, who directed 32 episodes of "Frasier" and 237 episodes of "Cheers."
- Marks the exact 20 year period since Cheers began back in 1982.
