Petition HBO could fill you in on 5th season of 'Sopranos,' but they'd have to kill you -San Francisco Chronicle headline Can we stop using the "I could tell you, but then I'd have to kill you" line, please? It gets mentioned every time a mobster movie or show or musical comes out, and I'm really sick of it. Not just there, though. Any time someone has a secret they don't wanna tell or wants a legitimate reason to murder you, this line gets whipped out faster than a bad reality show on Fox. Let's all put an end to trite mob quotations. I know it's an offer you can't refuse.
