Joke of the Day - Blood Circulation

A teacher was giving a lesson on the circulation of blood.

Trying to make the matter clearer, he said, "Now class, 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 class said.

"Then why is it that while I am standing upright in an ordinary position the blood doesn't run into my feet?"

Emma shouted, "Cause your feet ain't empty." :evillol::evillol::evillol::runaround:

Nice joke
