I still watch it.
What I find about the new episodes, they aren't very funny the first time you watch them...but when you see it rerun once or twice (which will happen within a month since its on so much, haha), its funny the second time around.
Kinda weird. At any rate, I still enjoy it, although I do think it's past it's prime (which I thought was seasons 8-12, later than most people think). 18 years and still going strong.
