Ever get the urge to look at pornographic drawings of famous cartoon children? Neither do I, but 28-year-old Kurt James Milner did, and that's what got him registered as a sex offender. Police received a tip about the pornographic material and eventually found images featuring child characters from The Simpsons and The Powerpuff Girls on Milner's computer. Back in 2008, a Supreme Court judge in Australia ruled that cartoons in which child characters engage in sexual acts is child pornography. Milner said he downloaded the images to show them to his friend 'because he believed they were funny.' Guess it's not so funny now.
