One for the Road (1) - S11-E26
Visible crew/equipment: When Rebecca leaves Don at the table to relax while she gets champagne to "celebrate the answer", it cuts to an overhead shot as we hear the TV host introduce Salman Rushdie and Dr. Ruth, and the set lighting can be seen as well as the boom and mic moving around at the top of the screen. A few minutes later the mic can be seen bobbing again in the overhead shot from the same angle. (00:03:20 - 00:08:20)
Revealing mistake: When Frasier comes into the chalet after skiing he doesn't show any of the visible effects after a hard day on the slopes. Meaning, his face isn't even flushed from the cold, his hair is perfectly combed after wearing a hat and there is not even a drop of snow on his boots.
Trivia: The portrait of Geronimo hanging in the bar was a tribute to Nicholas Colasanto after he died. The portrait originally hung in his dressing room.

Question: When I streamed this episode, there were a couple of small scenes missing (Sam explaining that his cigars were a gift from Fidel Castro via Reggie Jackson; Sam kissing Rebecca goodbye). I know they used to cut scenes to cram in more commercials after the initial broadcast, but with a streaming service, you're not limited to a time slot. Why not air the whole thing?
Answer: They sometimes acquire episodes from syndicated reruns. The ones with the cut scenes. Sundance channel have some episodes of M.A.S.H. uncut.
