The Fascinating History of Sign Language

I appreciate your interest, but I need to clarify something: based on the information provided, "The Fascinating History of Sign Language" appears to be a topic rather than a guest name. The episode you referenced (JRE #2095) featured comedian Moshe Kasher as the guest, not someone with that title. Could you provide the actual guest's name so I can write an accurate bio? Or if you'd like, I can write a bio for Moshe Kasher based on that episode instead.
