The Addams Family - Season 2 Episode 16
Uncle Fester, Tycoon

Fester gets a letter from another of his pen-pals, Diana the bearded lady. Overcome with emotion, he proposes to her by mail. Morticia is worried about him and poses as Dianas mother (complete with beard) to try and talk him out of it. She accuses him of being unable to support her daughter, so Fester decides he has to get a job. He enrolls in a correspondence course in business and starts getting into it. He gets very aggressive and hones his bargaining ability. He impresses Logan with his skills and is offered a job. Meanwhile, worried, Gomez calls in a psychiatrist, Dr. Brown, to help cure Fester. When Logan comes to see Fester, Gomez thinks hes the psychiatrist and that hes trying to take Fester off to an institution. Gomez manages to get rid of Logan, and Fester decides hes had enough of work and gives up on his plans to marry. When the real Brown arrives he thinks Festers crazy, but the Family thinks hes cured.
