I read about this on the Colbert Report thread on TWoP so I tried it:
http://www.20q.net/I picked TV and Logan was who I was thinking of. I did win, because the goal is to get it in 20 questions. But they did eventually guess it at 24 or 29 (I forget which one). It was so cool. Hahaha. I'm so doing other categories and faves!
ETA: Hee! I did Veronica. They got her in 17 -- first guess. They were sooooooooo trying to rule out Buffy first. Hee! Were you based on a movie? Do you use a sword? HAHAHA!!!
