A sample:

Fritz Kreisler had already gained immortality as a violin virtuoso when in 1935 he revealed that he was also a composer — for 30 years he had been performing his own compositions in concert but attributing them to Vivaldi, Couperin, Porpora, and Pugnani.
In the uproar that followed, Kreisler argued that as a young man he’d had no reputation; audiences would not have paid to hear the compositions of an unknown violinist. That was just the point, opined the Philadelphia Record: Fans had bought the pieces, and indeed other violinists had performed them, thinking them the work of established composers.
The Portland Oregonian agreed: “What if Fritz Kreisler had died without making confession that over a period of thirty years he had been composing music and signing to it the names of half-forgotten composers of former times? What if he had left no list of his works?”
Which raises an interesting question: How many such hoaxes have succeeded? How many of our great works of art are undiscovered forgeries?

And:

In Collectanea de Rebus Hibernicus, his 1791 disquisition on Irish antiquities, Charles Vallancey describes a group of sepulchral stones on the Hill of Tara, one of which is inscribed BELI DIVOSE, “To Belus, God of Fire.”
Vallancey goes into some detail interpreting this as an altar to Baal. It turned out later that a wanderer had lain upon the stone and idly carved his name and the date upside down: E. CONID 1731.
Vallancey’s reaction is not recorded.

And:

In 1999, UC-Davis civil engineer David Phillips was grocery shopping when he noticed something peculiar. Healthy Choice Foods was offering frequent-flyer miles to customers who bought its products. But a 25-cent pudding would bring 100 miles — the reward was worth more than the product itself.
Recognizing a good thing, Phillips bought 12,150 servings of pudding for $3,140, claiming he was stocking up for Y2K. Then he enlisted the Salvation Army to help him peel off the UPC codes, in exchange for donating the pudding.
He mailed his submission to Healthy Choice, and to their credit they awarded him 1.25 million frequent-flyer miles, enough for 31 round trips to Europe, 42 to Hawaii, 21 to Australia, or 50 anywhere in the United States.
There’s no downside. Phillips also got Aadvantage Gold status for life with American Airlines, which brings a special reservations number, priority boarding, upgrades, and bonus miles. And he got an $815 tax writeoff for donating the pudding.
