I <3 Family Guy... Seriously I need to sit on newspaper when I watch it.
I have every episode from the first 3 seasons on DVD and I've taped all the new episodes of season 4.
I can't really explain it, other than it's the most fast-paced cartoon I can watch without having a seizure. It's funny as hell, and you never know what to expect.
