Last December, pranksters set up a spoofed website for Koch Industries, America's largest producer of crude evil, and sent out a boring fake press release claiming they were reforming their climate-destroying ways. The super-sensitive billionaire conservative Koch brothers promptly sued them for a bunch of bullshit like "infringement of trademark" and "unfair competition." (Didn't know the Kochs were getting into the spoofing-themselves biz.)
Thankfully, a judge just threw out all their junk lawsuits. Go forth and prank, pranksters! And try to make the prank a little funnier next time.
