The good news is, I just took a player named Brain Hampton in the Arena League allocation draft. That's no typo. His name really is Brain.

The bad news is, his intelligence rating is 15.

guessing intelligence is not important for Secondary players.

This is one of my RBs. Also a Brain. With a little more of a brain though. I kept writing his name as Brian until I really looked at it.

Apparently there is 0.0013% of the population whose name is Brain, or 0.0013% of census workers entered their data incorrectly.

I think that equates to about 4000 Brains in the US. I'm guessing typo.

but does anyone have a "Pinky"?

Someone needs to rename one of their players!
