I heard about this gem while watch an episode of Seth Macfarlane's calvacade. Its about a guy in his 20s called Tim, who's life is pretty simple. I decided to watch some clips of it on HBO's official website, and I must say, I really enjoyed it in a weird kind of way.
The badly drawn characters, weird animation and humor was very amusing. I've never seen any full episodes of this. I don't have a clue which channel this program airs on in the UK.
Since I've not seen much of the show, I don't have much more to say. If you like cartoons that are aimed at more mature audiences, I suppose this show is worth a look.
