Martin: Thanks.
Frasier: Niles, what are you talking about?
Niles: You spoke to a patient of mine today, Caroline. As a result of your fast-food approach to psychiatry, she left me.
Frasier: Caroline was your patient?
Niles: Two years of my hard work wiped out by one of your two-minute McSessions.
Frasier: Niles, I merely suggested that she consider a change.
Niles: Based on what diagnostic method? One potato, two potato?
