The only cartoon I watch currently is Simpson, but that is only because they aren't showing South Park of TV currently. I was a big Dragon Ball Z fan in its hay-day, also got into Yu-Gi-Oh for a while which is actually partly responsible for my user name.
Loves me some Yi-Gi-Oh! - original stuff not the new junk, still have my card collection too, god i love that stuff!
Also Billy and Mandy, thats awesome ^_^
