I forgot one! (at least)
Full Metal Panic! (All seasons) - The best mix of action, romance, and comedy around, though season 2 (fumoffu) and 3 (TSR) seemed to separate the comedy and action... The first season though, it has it all! Now I hope that the cryptic tweets by the author about a project for 2013 that he cannot name that has a "long awaited" feel to it is actually the completion of FMP in anime!
For now, I just have to enjoy his writing in Hyouka.
