This reminds me of a story told by Sally Rogers.   She was once audited by the IRS.   Fortunately, Sally is a meticulous record keeper and had recipts and bills for everything.   After going through the audit, the IRS inspector actually discovered that they owed her money.   She had actually overpaid, and therefore got a refund check.

When the auditor finished, he told Sally he had just one more question. After looking at the small amount of income she had compared to all the work she did he asked her "Why do you do this"
