Paul Picerni guest stars as Jack Williams, an opportunistic -- and treacherous -- American POW. In exchange for his own freedom, Williams intends to give the Gestapo information on Hogan's underground activities. Hogan hatches a scheme to turn the tables on the turncoat. The episode's highlight is a brawl sequence -- a masterpiece of comic choreography. Written by Laurence Marks, "One in Every Crowd" originally aired on November 11, 1967. ~ Hal Erickson, Rovi
