Main Characters in this Episode
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.
Norm Peterson: My blood alcohol level.
- 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.
- 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.
