"Graft" is a throwback to the pilot, with one scene featuring Barney's flirtatious wife Liz in their apartment (Barbara Barrie's second appearance, no children this time). Dick O'Neill plays Inspector Kelly, formerly from the 12th Precinct, whose new position with Internal Affairs finds him searching for signs of graft among his old comrades (one repeat appearance in "Ambush"). Yemana's gambling comes under fire, Wojo's attempt at cheating during a sergeant's exam, even Fish, who made deductions for a trip on behalf of his wife Bernice (who did not accompany him). Barney worries about free tickets to Bermuda, and getting great deals on meat from a butcher who likes the way Liz walks. Chano pursues an obscene phone caller, talking to victims all over town, getting names, addresses ("I also got excited!"). Back from the pilot is Buddy Lester as Yemana's bookie Harry, arrested for convenience because Nick has been warned about gambling over the phone (one further appearance the third season, "Abduction," now named Sidney). Derrel Maury ("Massacre at Central High") pops in and out as a newsboy with the late edition, compliments of the publisher. One nice tidbit is Kelly asking about missing detectives Harris (Ron Glass) and Wilson (Rod Perry); Perry appeared in the filmed pilot and episode 2 ("Experience") but no more, while Glass played in the videotaped pilot and remained on the force all eight seasons.
