Arguing the Case for Fair-Use by Example?

bobej1977 asks: "Happened to be perusing my local newspaper website and came across a link to one of those corny news websites, a la Dave Barry. Included were a couple of funny Fair-Use related stories. This got me thinking about how it's often easier to explain the idea of fair-use in terms of the absurdities that occur when people stop using their common sense. Anybody else have any interesting links/stories?" Read on for examples of what bobej means. bobej1977's article examples:

"In December, Australia's TV Channel 7 reported that many schools across the country, at the behest of the Australasian Performing Rights Association, were discouraging parents from making keepsake movies of their kids' appearances in Christmas musicals, because recording the holiday songs might violate copyright law. [Seven Network Ltd. (Australia), 12-22-03]"

and

"In February 2004, according to a New York Times report, cuts from 'White Album' by the band Sonic Youth were being listed for downloading on Apple's iTunes online store, and included was 'Silence,' a 63-second cut consisting of no sound at all, for which fans were nonetheless expected to pay the regular iTunes price of 99 cents. (In a subsequent clarification, a Sonic Youth spokesman said 'Silence' would only be sold to purchasers who bought all of the album's cuts.) [New York Times, 2-9-04, 2-16-04]"

Are these decent examples of the absurd, that make a fair to strong case for fair-use? What examples might you have?
