TV's favorite father, Robert Young, is the guest panelist tonight, substituting for Ernie Kovacs, who's in Hollywood - maybe. Mr. Young joins the show's regulars, Arlene Francis, Dorothy Kilgallen and Bennett Cerf. Host John Daly asks the panel to don their masks, on the off chance that they can determine the occupation of the first guest by their apparel. As it happens, the first guest is the show's panelist, Ernie Kovacs. The panel tries to draw a bead until Dorothy Kilgallen asks the mystery guest if he is acquainted with anyone on the panel. Mr. Kovacs goes over to Dorothy and blows cigar smoke in her face, and she squeals. The panel is delighted at this duplicity, but Mr. Kovacs explains that he was California bound, but there was a mix-up with his travel arrangements and is leaving the next day. Next up, a Japanese woman, who is a member of the Japanese Senate. Arlene Francis zeroes in with laser beam focus and identifies the woman's occupation. John Daly asks the panel to wear their masks again for the mystery celebrity guest - Doris Day. It's Dorothy Kilgallen who truly identifies her, but Bennett Cerf asks if it's Doris Day. Miss Day, who is visiting New York, promoting her recent hit musical film, "The Pajama Game," chats with John and says how much she enjoys "What's My Line." Finally, twin brothers from Michigan, Michael and James Parisi, who are bartenders there, sign in. Miss Kilgallen again is about to identify them with her line of questioning, but it is the guest panelist, Robert Young, who asks if they are bartenders. Once the cat is out of the bag, Dorothy asks the brothers how they make martinis and squeals when she hears how strong they are. Mr. Daly thanks Robert Young for playing along this evening and Daly and the panel bid each other good night.
