It’s hard to fool Dorothy Kilgallen, but she gets off on a completely wrong track on this mystery guest, when Rosalind Russell disguises her voice.
The results are perhaps the most hilarious quizzing of a mystery guest that What’s My Line? ever saw.

But don’t take my word for it. Watch it for yourself.
I’ve queued the video to start at the entrance of the mystery guest, but the earlier regular contestants gave the panel a difficult time as well, so you might want to watch it from the beginning.

This is from January 4, 1953. Oh, by the way, Rosalind Russell was 45 years old when this show was broadcast.
