I assumed Kay was either fat and ugly, or some notoriously malodorous starlet that had somehow offended Johnny when she guested on his show. Though she did guest on his show, it 'twas the former. Fortunately for her, and Kate Smith, back then a lot of people simply listened to a lovely voice on the radio or on a record, and didn't care that much about physical charm. This was especially true of singers that specialized in ethnic numbers or "God Bless America."
Armen could've become a big star with the irritating novelty song "Come On-a My House." It was written for her by her Armenian cousin Ross Bagdasarian (aka "David Seville") and William Saroyan. It was the more pleasant-looking Rosemary Clooney who made it a hit. Clooney's singing style also had a lot more charm than Madame Armen…just listen to her strident "Ha Ha Ha" novelty.
It ain't over even after the fat lady stops singing. After enduring the song, you get Johnny Carson's Kay Armen joke from the Rickles roast. Remarkably, it got a solid 30 seconds of laughter…a tremendous amount for any joke. It's even more of an achievement considering Johnny was telling it in a room full of jaded comics more likely to mutter "That's funny" than to actually laugh. The dais that night included Flip Wilson, Jackie Vernon, and Jack E. Leonard, and you can hear some admiring mumbling from Fat Jack as everyone yocked the mocking of Fat Kay.
