Simple. I cloned the rice before you ate it, and gave one copy to R3APER, and kept the other copy I made. You ate the original.
So he did not eat the rice. He ate a reproduction of the rice. Therefore the rice is mine! xD
Dammit...
Sure, I'm putting some URAN on my RICE as we speak, because I think it makes the RICE taste good. Just be careful with those nuclear reactions...
