Visible crew/equipment: When Daphne is yelling from the kitchen door about Marty not storing his gun properly we can see pole-shaped shadows passing over her head on the shelves behind her. These cannot be explained by the actor's movements.
Goodnight, Seattle: Part 1 - S11-E23
Visible crew/equipment: (This is for the last episode, "Goodnight, Seattle.") When Kenny opens the door to use Frasier's bathroom, you can see a light pass across the wall above the fireplace.
Answer: Nanny G (Nanette Guzman - played by Laurie Metcaf) has been a children's entertainer for twenty years, and tells Frasier, "Do you know what it's like to play the same character for 20 years?!" The joke is that Kelsey Grammer has been playing Frasier Crane since 1984, when the character first appeared on "Cheers", so Kelsey in real life has been doing just that!
