Also, Inojin is one lazy name (doesn't "jin" mean "human"? "Pig human"?), and Chocho is even lazier. I find it unlikely that this is the first time someone in their clans used those names seeing how they've had that InoShikaCho thing going for generations.
Choji: Aw man, I don't think there are any more good names starting with "Cho" left! The previous generations used them all up!
Karui: Eh, let's just name it ChoCho and be done with it :|
