Brains are pretty neato. I recently read about a guy who had part of his brain ravaged from a disease. The missing pieces caused him to not be able to remember anything long term, except very, very old memories. Those were fine. Wild stuff. Here’s a somewhat melted brain atop a wood post, culminating in a brass tamping end. Great conversation starter. Have a few lines memorized for when you pull this guy out, the more punny the better.
