Anything with a run time of less than 20 minutes, and has 3 or more episodes is on this list. Including DVD/TV specials for longer run-time shows. The list is ordered with stand alone shows first...
Hmm just anime that you can put on that isn't full of action or drama. Just slice of life, comedy that sort of thing.
Order messed up.
Until the end of 2013.
Here are the anime I've re-watched at least once. It's possible that this list will get bigger.
