Tom had a problem. He could never get up on time and was always late for work. His boss threatened to fire him if he didn't do something about it. So, Tom went to his doctor.

Tom's doctor gave him a pill and told him to take it before he went to bed. Tom slept well and actually woke before the alarm. After a leisurely breakfast, he drove cheerfully to work.

"Boss", he said, "The pill actually worked!"

"That's all fine," said the boss, "but where were you yesterday?"
