I made this to entertain a few friends (Who are watching me type this...O.O) , and, well, it works.

Improv - How the Uchiha clan got their sharingan

Something I improved at, like, 11:00 PM at a sleepover.
Yes. I know. I'm really, REALLY, crazy.

Once upon a time (which was NOT in a galaxy far, far away), Madara Uchiha had wandered into a place where everyone had pink eye. Madara, as you can expect, caught that pink eye, and even after he was cured, the infection stayed in his system. After a while, he figured that out (Actually, he went and saw a doctor. The doctor told him that.) and was able to harness the power of the pink eye. When he had children, they had this spectacular version of pink eye as well. Thus, they were all able to harness the power of the pink eye. It has been told that there is an improved version of this pink eye, that can only be obtained by catching pink eye while using the pink eye. Thus, in the Uchiha clan's long history, it has manifested in only a few.
Thus, in conclusion, this is how the Uchiha clan got their sharingan.
