22-years ago Judd Apatow wrote a script for 'The Simpsons.' He had written it on spec, and at that point he had no writing credits. It's doubtful that the script was ever read, and, if it was, it certainly wasn't made into an episode.

Both Apatow and 'The Simpsons' have come a long way over those 22 years. During an episode of Conan O'Brien's web series 'Serious Jibber-Jabber,' Apatow explained that  'The Simpsons' producers recently caught wind of the ancient script and have decided to shoot it.

After only five Simpsons episodes aired, I sat down and tried to write one when I was in my early twenties. And what it was about was they went to see a hypnotism show and at the hypnotism show, they made Homer think he was the same age at Bart. And then the hypnotist had a heart attack. So now Homer and Bart became best friends and they spent the rest of the show running away because Homer didn’t want responsibility and didn’t want to be brought back to his real age. So I basically copied that for every movie I’ve made since."

Apatow has of course gone on to great success with films such as 'Knocked Up' and 'The 40-Year Old Virgin.' If only 'The Simpsons' had recognized his talent 22 years ago, his whole career would be another example of "The Simpsons' did it first."
