Dragonball Z, Bleach, Naruto, One Piece come to mind as shows with hundreds of episodes.

Do you watch any of those? More specifically, have you ever tried to start from episode 1 and catch up to present day? It would be hard with a show like One Piece, which I think has 6 or 700 something episodes.

I've seen Bleach here and there but I think I'm going to watch it from start to finish. Not a marathon, but just over time. I'd like to have one super long show to watch that I can periodically go back to and resume in between shows that have 12 to 36 episodes.
