My favorites:
1. Family Guy
2. Robot Chicken
3. Friends
4. House
5. Bones
6. Big Brother
7. Cheers
8. The Pretender
9. Will and Grace
10. Everybody Loves Raymond
No particular order. There are some that I left out, but those are the main ones. I either watch them and refuse to miss an episode, or own all the seasons on DVD. I prefer buying season dvd's because unlike movies, you don't have to commit yourself to 2+ hours of watching tv, and there are usually 20 episodes or more on the dvd, which makes for longer enjoyment.
