I watch random episodes of random seasons of the anime every now and then. I don't think I've seen too many episodes. Let's see... there's around 1000 episodes, so I'd say I've seen around 10%, or around 100 episodes. (I watched mainly Hoenn, Sinnoh, and Unova as a kid, I know for certain I've only seen 2 episodes of X and Y, I've watched some episodes of SM, I've only seen a few episodes of the original series, haven't watched the newest series yet but I might watch it.)
