Craziness. He guessed Brett Favre and Bill Maher on the first guess. Then I decided to go a little harder, and pick Ken Levine, and it failed (but, to be fair, I messed up on one of the questions, so that was probably on me). Either way, crazy website. Thanks for the find, OP.
Edit: So I was trying to get him to guess Ricky Gervais, and he asked if he was British. Afterwards: "Is he gay?" I see what you did there, Akinator.
