These days I only like a few TV shows, compared to when I was a little kid and all I did was watch TV/Play Games if I wasn't outside.
I'll watch TV once to twice a day at most.
Only shows that'll make me mad if cancelled:
Degrassi - I know it's downhill but I've watched it SO LONG it would be weird w/o it.
Family Guy - That show will NEVER go downhill.

I think it actually improves as it gets older because the jokes get better and wronger.
