Totally agree with this. A lot of it, imo, has to do with him actually respecting her and that she can be honest with him, just like a real friend--and he listens (re: Luann, for example. And she apparently doesn't know his friendship with Carol, but she was right "Get over yourself. You're on reality television, just like the rest of us.") Plus, their humor clicks.
I could watch a regular show with just Andy and Bethenny. They just have chemistry. I would rather see her do a regular slot than Sandra Bernhardt. She just fits the vibe of the show.
But what was up with that game? No crotch shots of Santas of the past? No double-entendre game title? No guessing if it's "Menorah or Men-whore-ah"? Or any other of his weird ideas. I mostly don't like his games but I truly didn't understand the point of giving B clues like, "He's the big jolly guy in the red suit that brings presents..."
But..yes..ITA they have great chemistry and she comes across much better on WWHL than on her own shows.
