His name was Brother and he went on to become a brother? Were they calling him Brother Brother when he was a monk? I hope so, I'm really hoping he didn't choose a new name when joining the monastery.
I think this is why this name makes me laugh so much because "brother" is such an impersonal non-specific way to refer to someone. It makes me think of monasteries and old-timey wild west and using "brother" when you neither know nor care what someone is named. Then to turn around and use it as a personal name is bananas. Like naming someone Person.
