On an episode of The Simpsons the heavy metal band Judas Priest was described as “death metal”. This created an uproar online with fans. When the show’s writers caught wind of the mistake, they apologized by having Bart Simpson repeatedly write “Judas Priest is not ‘death metal'” on the classroom blackboard at the end of the episode.
Here is a video clip of Judas Priest as they rock out on The Simpsons.
