Thread: kids are back.

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 up right in the ordinary position the blood doesn't run into my feet?"
A little fellow shouted,
"Cause your feet ain't empty."

oh dah...lol...took me minute..
