If our earlier comparison of Gender Trouble to Jaws didn't make you want to read this book, we don't know what will. Once you've encountered Butler's ideas, you'll never be able to think about pulling your pants on in the morning, or applying your lipstick, in the same way again. It's all a socially invented performance, people. Even the kitties know that.
Reading it, why not ask yourself: are gender performances intentional, or prescribed? What really comes first—the body, or discourse?
And if you really want to stick it to the structure, er, man, think about what sorts of acts of questions you have to perform as a socially constructed reader in the 21st century. That should get the wheels a-spinning.
