A childhood belief about rude bits

I would always beg my mother if i could have a little brother or sister, because being the younger child, i wanted to boss someone around. My mother told me that my father could not because he had a bisectamie. Well when i took my cat to get neutered,i realized they were the same thing. So the next night, when we were holding a small get togeather with our friends and family, i sat down and announced that i couldn't have a younger sibling because my father was neutered. My parents were flustered and sent me to my room.
