School jokes
A teacher was giving a lesson on the
circulation of the
blood. Trying to make the matter clearer, he said: "Now,
students, if I
stood on my head the blood, as you know, would run
into it, and I should
turn red in the face."
"Yes, sir," the
boys 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, "'It's because yer feet ain't empty."
