mystery comedienne

A premise of the 5/16/60 show was that there were no female comics on TV. Henny Youngman did his typical routine; then he and Steve wondered how a female would do a comedy stand up act. So, for an example, a brassy female came out and did a Henny Youngman routine exactly as Henny had just done it. (Is this an audience or an oil painting? Come on, I know you're out there! I can hear you breathing.) Henny and Steve shook their heads and agreed it wouldn't work. Who was the brassy female? The closest I can figure out, it was Joan Shawlee, Sweet Sue in Some Like it Hot.

If there is any interest in this topic, I'll tell you how they solved the problem.
