*South Park'*s 'What What (In the Butt)' Beats Infringement Claim

A federal appeals court affirmed Thursday that a 2008 South Park parody of a real-world video -- "What What (In the Butt)" -- did not infringe on the YouTube video of the same name. The decision upheld a lower court which sided with Viacom subsidiary Comedy Partners' fair-use defense. More important, the outcome affirms the right that you can get an infringement case thrown out of court -- via a fair-use defense -- without having to go through an expensive trial.
