Views(44) Created(8-9-07) Category ( Lists )

A teacher was giving a lesson on the circulation of the blood.
> Trying to make the matter clearer, she said, "Now, class, if I
> stood on my head, the blood, as you know, would run into it, and
> I would turn red in the face."
>
> "Yes," the class said.
>
> "Then why is it that while I am standing upright in the ordinary
> position the blood doesn't run into my feet?"
>
> A little fellow shouted,
> "Cause your feet ain't empty."
