I'm going to name of a bunch of good shows that should have never been taken off the air... Although I barely remember them... I remember them being great:
1.The Tick
2.Earth Worm Jim
3.Cow and Chicken
4.Undergrads
5.Clone High
6.Harvey Birdman
7.Animaniacs---v
Pinky and the brain
8.Aaagh! - It's The Mr Hell Show
9.Sharkie and George(How ever little I remember of it)
10. Dilbert (It might still be on at like 3 in the morning)

That's all I remember for now... If you have anything you think should be added to the list feel free. Remember, I live in Canada, so you might get some of these shows but I don't.
