I gotta throw down my vote for Scrubs, as well.
If that show never wins an Emmy, it will be a crying shame. John C. McGinley is fucking awesome on that show. It's a fucking comedy, yet his acting is better than most drama shows. So is the rest of the cast's, to be perfectly frank. Why uber-hot Sarah Chalke is not appearing in anything else with her hottness baffles me.
I have a thing for Conan O'Brien, as well. He's more accessible over here in Australia, so I can catch all his shows. The guy's a comedy genius.
I'm also a fan of the Law & Order shows as well. For those of you who enjoy the shows, or like the show Oz, I recommend Homicide: Life on the Street on DVD. One of the greatest shows of all-time.
