The chemistry between Tony Randall and Jack Klugman, Best Actor Emmy nominees is the real attraction in the fourth season of The Odd Couple. They are so thoroughly at home in their roles that they elevate the more over-the-top material, as witness their ill-fated presentation as glue entrepreneurs in A Barnacle Adventure. Among the seasons best episodes are the ones that go back to the basics of Neil Simons warhorse play: Can two divorced men share an apartment without driving each other crazy? Zinger-queen Brett Somers returns as Oscars ex-wife, Blanche, in flashback episodes that continue to play havoc with Felix and Oscars backstory (so now they were in the Army together?) Randall, Klugman and company (including Penny Marshall as Oscars secretary, Myrna) clearly relish playing to their enthusiastic live audience, and this richly entertaining season is brimming with classic moments and bits of comic business that continue to bring down the house.
