In 1979, an episode was done with the actors out of character as a tribute to actor Jack Soo, who played Det. Nick Yemana. Soo had died of cancer of the esophagus in 1979. The episode consisted of unscripted reminiscences of Soo by the cast members, interspersed with clips of him from the show. At the end of this episode, the cast raised their coffee cups as a salute to him, a reference to the running joke throughout the series that Yemana always (but unintentionally) made very foul-tasting coffee for the other members of the squad.
