I *think* I watched the first season of Jigoku Shoujo twice.
Seen the first 2 seasons of Shugo Chara! 2-3 times and rewatched Amagami SS and Amagami SS+ 3 times.
I'm planning on rewatching Fate/Zero too.
Oh and I've rewatched episodes from many animes but I don't think that counts here and even if it did I wouldn't be able to remember how many times lol.
