Tiny Toons and Animaniacs were two of my absolute favorites... those early-mid 90's WB shows were all fantastic. Also a big fan of "Pinky and the Brain."
(There were SO many good cartoons in the 90's...)
Oh yes, and I don't know if anyone is interested in discovering some new animated shows that are really good or not, but over the last week or so I started watching "Gravity Falls," and I VERY highly recommend it. It's extremely funny, creative, and has really good characters too. (Episode 1 is kind of meh, but once you get to episodes 2 and beyond, it is freaking AWESOME!)
