websites like watchcartoonline.com that have every cartoon/anime?

[Thobias]

http://funniermoments.com is a pretty good one if you have decent good internet, being that the shows are in such high quality. Here you can watch all the episodes of Ed, Edd n Eddy and other older Cartoon Network and Nick shows. Their shows are in order.
If your internet connection is not super good, try http://dubbed-scene.com.
They are more like watchcartoononline. They've got all the newer shows. Family Guy and such.

For you anime needs, try http://animedubbedonline.net.
They also have some pretty good anime over at http://crackle.com.
Then there's http://theanimenetwork.com.

Crackle, TheAnimeNetwork and FunnierMoments are not bootleg and therefore most of their shows are in much higher quality.
