I honestly chose Billy the Kid over Apanuugpak too. I don't know why, but Apanuugpak never pulled me in like Billy the Kid did for me. Don't get me wrong, Apanuugpak is a GREAT episode. But like Brent said, it wasn't as memorable to me as Purple Parrot Pwnage. I know that Gator was the star of this episode, but the earlier rounds weren't very memorable to me. The temple win was great though and I can't deny that Gator was the best player on the show.

But at the end of the day, Billy the Kid is more memorable to me.

I like the PP Pwnage storyline and I found myself rooting for Kelly and Tony when I first watched it. Apanuugpak is a great episode, but the episode was never really in my top 10. Billy the Kid is on the other hand.
Go Purple Parrot Pwnage!
