China, China, China. Come on now my love. Splinter was a bit of a disciplinarian, and was constantly getting annoyed with Michaelangelo's lackadaisical attitude to his ninja development.

Donatello was not so much a geek, as just plain intelligent which I'm sure made him a hit with the ladies as well. April O'Neill always had a bit of a soft spot for him.
