We've spent a lot of time (especially on the old forum) picking Frasier apart and finding little mistakes. Fun as that is, I thought we could list some of the examples of good continuity (maybe even way back from Cheers as well!).
Some little things I remembered:
- Daphne mentions her brother Billy a few times, each time to say he is a ballroom dancer and nicer than her other brothers.
- Gil's wife is portrayed as pretty tomboyish twice: once when he said that she owned an auto body repair shop, and another time when she was on maneuvers with her reserve unit.
- We see Bebe struggle to quit smoking in Where There's Smoke, There's Fired and starting it again at the end of the episode. We also see her smoking again in Morning Becomes Entertainment.
