I saw it...
Yes, they did show it. The tickling was rather interesting. Howard's crew put her in the "Laughing Stock", and Howard tickled her on her sides and underarms near the end of the show. But while he was tickling her, she grabbed a hold of his hair with her teeth and bit some of it off. This didn't please Howard very much, so he eventually kicked her and her producer out of the studio.
I had no idea who Rhonda Shear was until I saw that episode. After having seen it, I can now say that in my opinion, Rhonda Shear is a complete idiot with an incredibly annoying personality.
Don't get me wrong; she's pretty...even though she wears a wig.
