Emily wants Bob to accompany her on a two-month European cruise. Bob is reticent, fearing that his practice and his patients will suffer during his absence. The crisis is resolved with a stateroom scene that would have done the Marx Brothers proud. Longtime Tonight Show head writer Pat McCormick appears in a cameo role. Written by Austin and Irma Kalish, "Bum Voyage" originally aired on March 3, 1973. ~ Hal Erickson, Rovi
