Trivia: Lisa Kudrow auditioned for the role of Roz. She had actually appeared before in an episode of Cheers, when she played a character called Emily who was giving Woody acting lessons. Peri Gilpin, who got the part of Roz, also played a reporter in Cheers season 11 - "Woody gets an election."
Continuity mistake: Martin goes out to a baseball game with a famous writer that Frasier and Niles admire. While he is out, they read one of his books he accidentally left behind. When the author returns, he ends up holding the pages of the book in his hand, whilst standing in front of the fireplace. In one shot he is holding them in his left hand, but when the view cuts to another angle, he has them in his right hand. This occurs just before he goes outside to throw the pages off the balcony.

Continuity mistake: At the end of the episode after Sam mentions stewardesses he claps his hands, and his seat belt (which was caught on something) moves across his chest to the regular position. Cut to a wide shot of the car and Sam's seat belt is back to the position it was in before. (00:21:05)
