I'm not really a big fan of the sort of meta cartoons you see on Adult Swim. Most of them just seem really stupid. The only one I ever cared for at all was Sealab Something-or-other.
But for some reason, I just *love* the very meta Axe Cop. I love it because it acts like it's the stream-of-consciousness ramblings of a hyper 8-year-old brought to life. It makes no sense, but it makes perfect dream sense. It is often quite heartless and always wildly funny.
There have been two seasons so far and only a handful of episodes per season, so while it is possible that this joke could get old eventually, at this rate I could watch it for years. ADDENDUM: darn, cancelled after 2 seasons.
