Once upon a time there was a female brain cell, which by mistake happened to end up in a man's head. She looked around nervously but it was all empty and quiet.
"Hello?" she cried, but got no answer.

"Is there anyone here?" she cried a little louder--still no answer.

Now the female brain cell started to feel alone and scared and yelled at the top of her voice, "HELLO, IS THERE ANYONE HERE?!"

Then she heard a very faint voice from far, far away...

"We're down here."
