Frasier (1993) - 10x07 - Bristle While You Work (1)

Niles becomes concerned about a lingering toothache after his dentist assures him that there is nothing wrong with the tooth. He tells Roz that there is a chance that he may be suffering from referred pain; and that the pain could actually be a sign of a heart condition. Roz mocks him upon learning that there is only a one in 10,000 chance of this. However, Niles worries even more after experiencing a series of astonishingly improbable events--such as having his car struck by lightning, and twice winning a contest from a bottled water company for which there is only one winner in 10,000. He goes to see a doctor, who confirms his worst fears by telling him that he must be hospitalized immediately due to an irregularity in his EKG. Meanwhile, Frasier has difficulty finding a suitable housekeeper to replace Daphne. Martin is impressed by a young woman who is a sports fan; and insists on hiring her, in spite of Frasier's objections. However, she proves to be totally irresponsible, and rarely even shows up for work. Martin tries to handle all of her duties himself so that he won't have to admit that Frasier was right about her.
