Subject: longest nerve in body
Did you know that in the human body there is a nerve that connects the eyeball to the anus?
It's called the Optirectal Nerve, and it is responsible for giving people a shitty outlook on life.
If you don't believe it, pull a hair from your ass and see if it doesn't bring a tear to your eyes.

Keep laughing... it's the only way...
