Andrew Prine guest-stars as George Whitman, a self-proclaimed "jinx" who inadvertently leaves disaster in his wake wherever he goes. Over the protests of the Ponderosa ranchhands, Whitman is hired by Hoss Cartwright, who is determined to prove that George's hard-luck reputation is undeserved. But even Hoss has second thoughts when the dire predictions of gypsy fortune teller Teresa (Angela Clarke) begin to come true. Originally telecast on May 9, 1965 as Bonanza's 200th episode, "The Jonah" was written by Preston Wood. ~ Hal Erickson, Rovi
