I seem to run to Žižek more and more often -- frankly he is the only currently alive philosopher I can name. I really should read something more from him.
Zizek has written a lot of really fun and interesting books. I'd definitely encourage you to check him out, but just a word of warning: if he's the only living philosopher you can name, then you probably don't know enough philosophy to really understand everything he's saying. He assumes a pretty thorough knowledge of a number of past thinkers, like Marx, Hegel, Lacan, etc.
Do check him out anyway though, and also check out some general introductions to philosophy if you find yourself intrigued and wanting to learn more.
