This is my little brother's belief:
He used to tell us that he had a secret other family that he went to at night. His father was Pete, a fat man with a mustache and a bowler cap. His mother was Chip, a lady who always wore her hair in a ponytail. Then there was his sister, Flower, and his baby brother, Chuck. When he was bored with them, he would give us the news that they had all died in a freak submarine accident. Two weeks later, he would report that they had been found among the wreckage without injuries, and that they were alive and kicking. When I inquired how he could have two families, he proposed that he had been born by two mothers. Half of him had been born from my Mom, and the other half was from Chip.
Yeah...he was weird, all right.
