I imagine some random Ninja, walking up some piles of rocks and see a corpse with a sharingan.. he thinks. "WOW HOW PRETTY"
Run back to the village and bring the finest medical ninja
"I WANT I WANT"
And get it implated in his left eye soket.
But the "finest medical ninja" was nothing more then Intern Nurse Anesthetists
That poked his brain during the procedure, he lost all the comon sense
When he first opened his eye, he saw a "kite (bird)" that in japanese is called 鳶 【とび; とんび】(TOBI!)
He liked the name and kept.
So its purely concidencial that the people dead was called Obito =p
