I know. Usually I don't like the kind of humor where they just try to see how offensive they can be, but Sienna has a style that I really like for some reason.

There's something gleefully exuberant about her performance. Also, she presents herself as a degenerate laughing with fellow degenerates, as opposed to a lot of epater-le-bougouisie types who do this sort of thing to prove that they're better and braver than the average dickhead. That ain't Sienna, though.
