Season 3: Episode 58: The One Where Rachel Quits
When Gunther has to re-train Rachel on her duties as a waitress, Rachel realizes it's time to quit. The guys encourage her quit even though she doesn't have another job lined up, saying she'll need "the fear" of not having a job to make her find a new one. Rachel quits and panics when she can't find a job. Joey tells Rachel of a secretarial position in fashion, but when Rachel gets the job it's no better than her last one. She's still making coffee, only this time for an executive in the fashion industry. Ross accidentally breaks the leg of a girl scout selling cookies. Feeling guilty, he tries to help by selling her cookies. Joey has a job at a Christmas tree lot and Phoebe is horrified to learn that they destroy the trees that don't sell. In her eyes all Christmas trees have a mission, to spread Christmas cheer--destroying them before they fulfill that mission is cruel. To cheer Phoebe up the gang fills Monica's apartment with old Christmas trees that haven't been sold.
