Guy tries to get copyright lawyer's video taken down - for copyright violation

An Australian record label may have picked a fight with the wrong guy. The label sent a standard takedown notice threatening to sue after YouTube computers spotted its music in a video.

It turns out that video was posted by one of the most famous copyright attorneys in the world, and Lawrence Lessig is suing back.

Lessig, a Harvard Law School professor, has lectured around the world about how copyright law needs to adapt to the Internet age. In his lecture, he shows examples of people who have used the Internet to "share their culture and remix other people's creations."

One of the examples he likes to show is a series of remixes that use the song "Lisztomania" by the French band Phoenix. Someone remixed that song with clips from the iconic '80s movie The Breakfast Club. The remix went viral and inspired other videos in which people pretended to be Breakfast Club actors dancing to the song.
