While judges Katy Perry, Luke Bryan, and Lionel Richie are superstars known all over the world.<br />Sunday night, however, the 3 American Idol judges came face to face with a contestant that wasn't quite sure who they were.<br />Lou Dawg, a surfer from Oahu, Hawaii didn't know Perry's last name and confused Bryan with Justin Timberlake.<br />Richie was so offended he jumped out of his chair saying he's been in the business for "243" years.
