The stockbroker received notice from the IRS that he was being audited. He showed up at the appointed time and place with all his financial records, then sat for what seemed like hours as the accountant pored over them.

"Why would you say that?" wondered the broker.
"Because you've made more brilliant deductions on your last three returns than Sherlock Holmes made in his entire career."
