Akinator, the Web Genius

Its sorta like 20 questions. You just think of a person/character etc and let akinator ask you questions about them. Its pretty good. He has correctly guessed anything from Tony Stewart, to Dominic Toretto, to Eric Draven in 20 questions or less.

I've only gotten him to go more than 20 questions on Noah McManus (Il Duce), but the 21st question he asked was "Is your character Irish", at that point I knew he had me.

Try it out and see if you can stump him.
