I love this show and was very sorry to see it canceled. It was like a low-brow Seinfeld. Instead of clean-cut, comedian like Jerry, George Carlin's character is a rather sloppy, unbathen cab driver. He's a single guy with his circle of wacky friends. Action usually takes place in his apartment or in a local bar that his friend's gather at (which is sort of like Monk's as a hang-out spot in Seinfeld). I enjoy Carlin's Stand-up comedy, but he's always pretty funny when he takes on an acting job (he out-shines Bette Midler and Shelley Long in Outrageous Fortune).
It would have been nice if the show lasted longer. I have one episode that I taped off the TV that I drag out to show friends. It always yields laughs. I just wish I could fine a place to buy or watch the other episodes.
The comedy isn't for everyone. I wouldn't recommend it for people who like shows such as Friends or Mad About You.
Edit: I found a place on AOL to watch it, but you can see where Fox dubbed in other words (apparently they found the show too offensive). You also need to watch commercials, but at least it's available somewhere. I'd enter the link, but I don't think it's allowed here.
