Karl Sharo's parody of Zizek HERE. Representative sample:
Romney’s choice of words was very interesting, in the sense that Freud described when he developed the idea that what is said is not important, but how you can reinterpret it. To remind ourselves, Romney said ‘I love Big Bird’. Love. Curious choice of words. Love is the word we use to imply gluttony, as in ‘I love McDonald’s’ or ‘I love Dunkin' Donuts’. The Republican candidate wasn’t making a reference to public funding cuts directly, he wants to devour the flying nemesis, the feathered image of ourselves that has been repeatedly defeated since Icarus.
There is an interesting performative contradiction to this kind of thing. You would have to know Zizek pretty well to know if it's really funny (I don't and I don't), but anyone who knows Zizek that well is likely to be so invested in him that they are unable to appreciate the humor, if it is indeed funny.
