A man had a problem sleeping at night, and thought it may be his conscience troubling him. He knew that he had been less than honest when filling in his tax return, and maybe that was the trouble.

So he sent a check to the Taxation Department with a note that said:

"Dear Sir, I have not filled in all my income for which I should have paid tax. Therefore, here is my check for $100, and if my conscience still bothers me IŽll send you the rest."
