I seriously think they're building towards Bobby wacking off Tony in the series finale and him taking over the family, with Janice as sort of the power behind the throne. I'm not even kidding about this, it's a story thread that's been building for years - she was conspiring with Richie Aprile, and then with the Joe Pantoliano character (I forget his name).
She is so obnoxious that it really does make me wonder how much of it is acting. Also, I hate her character so much that it detracts from the show. That said...i hate you and your fucking spoiler. it dropped down when i was trying to skip it. assholespoiler (click to show/hide)... it was hilarious when Bobby beat the crap out of Tony![close]
