A professor was giving a big
test one day to his students. He handed out all of the tests and went back to
his desk to wait. Once the test was over, the students all handed the tests back
in. The professor noticed that one of the students had attached a $100 bill to
his test with a note saying "A dollar per point." The next class the professor
handed the tests back out. This student got back his test and $56 change.
