I think you're (for values of 'you' including allthelivesofme) right about it being sexist, but when I watched it, I felt like the sexist part was that a woman isn't a woman if she isn't in a short skirt. It didn't play like an assault to me, maybe because it looked more like pulling aside a curtain than ripping off someone's clothes.

The most WTF-did-I-really-just-see-that moment was that thing with Craig Ferguson, actually.
