Frasier: 10 Guests Stars You Forgot Were On The Show
9. Dr. Phil
Formidable TV personality Dr. Phil appeared in 2003's episode The Devil & Dr. Phil. The 21st episode of Season 10 introduces Dr. Phil as sharing the same agent as Frasier, giving Frasier a craving for a career like his.
Frasier is said to be friends with Dr. Phil from various seminars over the years, so introduces superfan Roz backstage to him. Sadly, Dr. Phil is too busy to reconcile over dinner. He states that his agent has him working around the clock, and uses the idiom "speak of the devil" to describe agent Bebe Glazer.
His phrase becomes literal when Bebe later tries to tempt Frasier into a hellish schedule comparable to Dr. Phil's while looking rather hellish.
