Whoh. I still believe in santa but this exactly what I do to prove my point.

Omg! xD how could seven year old Riku come up with all that?!
Thank you for posting!

awesome man! ... just awesome!
couldn't stop laughing... AWESOME!

... Ummmmm... wow. That's uh... that's a lot of math there. Ummm... I can't think of anything else to say, really. Thanks for the info!
... I think...
*brain explodes*

OMG! RIKU WAS A SMARTY-PANTS IN THIS STORY! xD

This is hilarious and I can just imagine Sora's face. I really want Riku to meet and have a conversation with Santa. I remember in KH II that Sora was embarrassed even when he did nothing wrong except by accident. But with Riku who told Sora Santa didn't exist, that would be hilarious. I have one question, did you actually do the math with the reasons or pick random numbers? Either way, this was great.
