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.’
