Made an account on www.Myanimelist.net, and I have to say. It is a pain in the ass to try and remember anime you watched over a decade ago.
Was a little god smacked when I realized that I had watched the entire Inuyasha series. Not just because it really isn't that great of a series. But because watching every episode worked out to 62.2 hours spent, and I know I watched a few of those twice -_-.
