Azumanga Daioh is one of the definitive animes of the 2000's, and deservedly so. Azumanga is a great slice-of-life anime, which means that it shows the viewer the everyday lifes of the characters. In Azumanga Daioh's case, the characters are six high-school girls who must have the most interesting teachers of all time. In between Yukari's drunkenness and Kimura's lust for underage girls, the girls somehow seem to stay sane and take their senseis' antics in stride.
Azumanga is as enjoyable as the first viewing even after many re-watches. it just never gets old. In my mind, and surely many other's, Azumanga is one of the best animes of all time.
