I would have thought the producers of Frasier would have learned their lessons after Bill Gates guest-starred on a previous episode.
Dr. Phil cannot act and this stunt-casting episode just takes a lot away from the feel of the show. Had a real actor been cast as a famous TV doctor, the hilarity could have been far greater than what was seen here.
The only real saving grace was the return of Bebe, and advancing the 'she is Satan' joke to the next level. Her attempted seduction of Frasier was classic and the best part of the whole episode. Stunt-casting should be re-evaluated.
