Not stepping into the mire of "anime is not mere cartoons", I just want to point out here that the "Gokou" spelling of Goku's name is not correct. Trust me on this, I speak and read Japanese with some proficiency here, and I have the untranslated manga. The furigana over the kanji of his name reads, when broken down, thusly: Go-ku-u. So technically, Gokuu us the most correct way of spelling it in English, and that shortens to Goku just as easily.

Pinky (the Brain's cool too)
Jessica Rabbitt (no one draws figures like her anymore and I've always been a sucker for Kathleen Turner's voice)
