sheep brains 

to view one's testicles in such a manner as they vaguely resemble a brain.

Ray showed the police sheep brains right before they arrested him.

Sleep Brain

This is the evil part of your brain in the morning that tries to trick you into sleeping in. It often attempts to fool you into thinking you've already woken up by making you dream about getting ready for work.

Dude, I'm late for work! I think Sleep Brain turned off my alarm this morning, cuz I don't remember doing it.

Charlie Sheen's Brain 

something you cannot handle for more than 5 seconds, causing you to "unplug this bastard". Charlie Sheen's Brain is like this, due to it being filled with tigers blood, the consistent banging of seven gram rocks, and insane amounts of Winning and bi-winning.

(You probably couldn't handle Charlie Sheen's Brain anyway, because you didn't bring enough gum for everyone.)

Normal Boring Guy 1: "Dude i tried using Charlie Sheen's Brain, but i was like "DUDE CANT HANDLE IT, UNPLUG THIS BASTARD."
Normal Boring Guy 2: "Maybe you should have brought enough gum for everyone"
