Ha! Chewbacca will do it; despite the fact it would keep asking me if someone walked on two legs and if it was an animal or not, I don't remember one questions about the character being an alien (or Wookiee! ;-)) or not! We could not stop playing last night, my sister and I just sat there thinking of people to put in there! We were most proud of the ones that were actually in their database and it still didn't guess (I'm guessing Chewie was like that? :-D)
