Once upon a time a female brain cell, by mistake, ended up in a man's head.....
She looked around nervously, because it was so empty and quiet.
"Hello?", she cried, but there was no answer.....
"Is anyone here?" Still no answer......
Now the female brain cell started to feel really scared,
and she yelled as loud as she could, "HELLO!!! IS ANYONE HERE???"
And finally, she heard a faint voice from far, far away: "We're down here."
