Pokemon was awesome.
Yu-gi-oh was cool, before all these spin-offs.
Lol, we use to follow the rules we saw in the show, and it was completely wrong, but we didn't care =P
I remember liking to watch the Powerpuff girls. XD
Also, there was this show (I think on Nick) called "So Weird".
I used to love that show. Never heard anything about it since.
