So Leo asked if I would take a stab at this one, so I will. It's going to be short and the ones that will matter most will be in the top 10 or so.
1. Upright Citizen Brigade
2. Arrested Development
3. Space Ghost: Coast to Coast
4. The Adventures of Pete and Pete
5. The Kids in the Hall
6. Quantum Leap first three seasons (just try and say it wasn't awesome)
7. Twilight Zone
8. Twin Peaks
10. SNL (Select seasons like Orig cast, 80's with SCTV crossovers and the 90's heyday)
10. The Critic
11. Home Movies (althoug I haven't seen too many, I love every one that I have)
12. Curb Your Enthusiasm
13. South Park
14. Freaks and Geeks
15. Ali G
16. The Venture Bros.
17. E.R. (early years with Clooney and orig cast... young Noah Wyle was the SHIT)
18. Danger Mouse
19. N.Y.P.D. Blue (seriously, really great)
20. Law & Order (Orbach, Waterson years)
Sliders for comic value, Animaniacs/Pinky & The Brain (I need to see a DVD of this show to see if I still like it), Salute Your Shorts, Working (short lived sitcom) and various Comedy Central Sketch Comedy shows like Reno 911 and Viva Variety. I am bad with newer tv shows, so its hard for me to include them. Also, random eras of ABC Soaps as I was forced as a child to watch All My Children and General Hospital. I can still follow storylines. Also, pro wrestling, which is basically soap operas with spandex and Pile Drivers.
I'll stop there as the rest will be a stretch.
If you have questions, concerns or want to talk about shows, comment me. Otherwise, thats the list.
