Jack: „My brother was sick and
went to the doctor.“
John: „Is he feeling better now?“
Jack: „No,
he has a broken arm.“
John: „How did he break it?“
Jack: „Well,
the doctor gave him a prescription and told him no matter
what
happened, to follow that prescription. And the prescription blew
out of
the window.“
John: „How did he break his arm?“
Jack: „He fell out
of the window trying to follow the
prescription.“
