For some odd reason my brother thought he was the reincanation of Inuyasha, a cartoon character.
He would sometimes ask our Mom when he would inherit the sword "Tetusaiga" and where did Dad get fangs anyway?
If someone found broken glass on the schoolyard he would pick it up and say "Don't tell the teacher! It's the shards of the Shikon Jewel!" When they insisted it was only glass he went to tell the teacher that they were trying to steal the jewel shards.
He was a very mixed up kid.
