Simpsons Season 4, Episode 19: The Front

After watching a terrible lackluster episode of The Itchy & Scratchy Show, Bart and Lisa decide to start writing their own episodes and sending it to the studio. Roger Meyers, the CEO, immediately rejects their script due to their age. They put Grampa's name on the script and send it back, and Meyers loves it and hires Grampa. Bart and Lisa's cartoons are hugely successful and are nominated for an award.
