Many South Park fans remember the 2008 “Canada on Strike” episode, which celebrated/parodied some of the Internet’s biggest YouTube sensations. The “Chocolate Rain” guy, dramatic gopher and "Star Wars kid" were all portrayed in the episode … but none of them are the one who’s suing the show.

South Park, cable network Comedy Central and parent company Viacom are being collectively sued for copyright infringement of the YouTube hit “What What (in the Butt).” The video, which has scored over 33 million views, was re-made on Park, with Butters playing the role of YouTube singer Samwell. The video above shows a comparison of the two videos, highlighting the similarities.

Coming so recently after the Park creators were forced to issue an apology for copying content from CollegeHumor.com, this looks kinda bad … but they actually might not be breaking any laws. Comedy Central released a statement that says the show is “fully protected against any copyright infringement claims under the fair-use doctrine and the First Amendment and we plan to vigorously defend those rights."

South Park famously spoofs movies, videos, television shows, celebrities and anything else it pleases. In the same episode, the animated series presented shot-by-shot remakes of several other YouTube videos as well.
