PIKATSSO, it's a matter of filtering. Instead of a being a suburbanite, Bonnie McFarlane is a woman who's lived and hung out in cities for years--mostly in an atmosphere with men. We are also seeing her in that article through the filter of another urbanite who is trying to come off as sophisticated in that silly Metro rag. A "sophisticate" who is sitting with Ms. McFarlane in a strip joint while most of the action of that story is going on. Now, I don't know if you've ever been in a place like that, and I'm hardly a regular, but when I have been and I've seen women as customers there they frequently seem to be assuming a demeanor which isn't totally their natural personality--and that's also part of what that article may be giving a peek into.
Also, your comparison of her to Kerry Louise assumes that it's a case of them being equally funny, and that Bonnie was chosen because she sleeps around and/or fits some demographic. It's possible, I suppose, but I don't see much proof. There certainly wasn't any indication that she was one of the people Drew Carey was talking about--who didn't get celeb votes.
Now mind you, I also liked Marina Franklin--who's approach was the polar opposite of Bonnie McFarlane's. The thing these two women had in common for me was that they were both the antithesis of the crappy approach I loathe so much of female comics with identical delivery and material.
Likely, you are never going to like or agree with Bonnie McMarlane's material. And I know from experience that watching her in the house could totally change my perception of her (or not). I like people to have a native wit--stripped away from the structure of those formal stand-up jokes--which is why I hated Dat Phan so much and loved Dave Mordal. And it's not obvious yet who in this group does and who doesn't.
And the things you are talking about ("give me some FUNNY") are SO subjective I can't see how you can back it up. This isn't a case like Sue Costello, where she was SO washed up and godawful that it was like a vision we could all see before us. Heck, even Costello probably had people watching cheering her on, as hard as that is to believe.
The "blue" issue is such a non-issue I don't really know what to say. She knew it would be bleeped on TV--I don't think that even as her worst we can consider her enough of an idiot to not think so. That's a safety net. Even Buddy Hackett--who was famous for having very different decorums between family audiences and non-family audiences--cursed on TV on occasion if he knew for sure that it would be bleeped.
