So this is my favorite anime of the moment now. I watched more that 35 episodes this weekend. It is by far the most comedic anime I've watched yet it still had action elements.
The animation is dated but I don't care. I could tell without looking it up t was from the 80's and 90's because Dragonball looked like that at the beginning. Looks like there are 1616 episodes so I've got a while before I am done.
The background plot is that Ranma, a teenager, and his father were were training is China where they both fell in to cursed springs. The father fell into the "Spring of the Drowned Panda" and turned into a Panda. Ranma fell into the "Spring of the Drowned Girl." So you can see where some of the humor might come from. Hot water turns them to normal but any other time they get wet they change into the alternate forms. The other main plot point is that Ranma's father and the head of the Tendo Dojo promised that their children would marry and take over the Dojo. Tendo has 3 daughters and the youngest is voted to be the best candidate.
Throughout the show there are a lot funny moments related to Ramna's curse in particular and the love/hate relationship with his arranged fiancee.
So if you haven't seen it is worth a look. I will warn you though, there's a fair amount of Ramna with no shirt on as a girl but nothing sexual. Just awkwardly funny.
You can find the whole series in Japanese with subtitles and Anime Freak dot TV.
