Radio characters didn't come daffier than Irma Peterson, the scatterbrained secretary who never met a phrase she couldn't twist. And Irma had one of radio's best straight women in roommate Jane Stacy. Together, they made wonderful radio comedy in My Friend Irma. Marie Wilson and Cathy Lewis star in this week's bonus comedy show; we'll hear a pair of episodes originally aired on CBS on March 15, 1948 and April 19, 1948).
