When Maris to goes to the hospital for some cosmetic surgery, Frasier (Kelsey Grammer) pays her a visit. He also runs into an ex-policeman named Artie (Lincoln Kilpatrick), who is also having an operation -- and who happens to be the former partner of Frasier's dad, Martin (John Mahoney). Aware of the quarrel that drove Artie and Martin apart many years earlier, helpful Frasier tries to stage-manage a reconciliation. The "guest-voice" cast in this episode will give a kick to fans of Singin' in the Rain. ~ Hal Erickson, Rovi
