Joke

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 louderstill 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."
