I knew several animes, although sadly mostly it's just the kiddie-shows or the definately-not kiddie-shows that are most know but there are several others inbetween, some plain comedy ones, some dramas worthy of oscars. I wish there was an aviation-one like there are for cars, éX-Driver, Initial-D, Over Rev! (ok that last one is just a manga, comic) etc.
I think I know Ranma but haven't really seen more than trailers or screenshots, I'll take a look at AnimeNfo.com for specifics. Gold Digger is also a story right? I'm reading a lot of webcomics and a couple of them are running a long crossover at the moment, very interesting. Published comics (as some of the webcomics actually are as well) have made some april fools jokes where they've swapped strips to joke the readers, some were posted in the very long-running danish Beetle Bailey magazine, like Garfield visiting Blondie and eating his sandwhich
Edit: Ok I just checked, yes Ranma was what I thought it was, at least the base story. I also found Gold Digger but it was webcomic related (or at least it was I think).
