The episode, called "Bart's New Friend," does sound like a classic Simpsons plot: Homer is hypnotized into thinking he's 10 years old, and after becoming buds with Bart, doesn't want to go back to adulthood. In an interview with Entertainment Weekly last year, Apatow also explained why he wanted to return to the script. "The reason I brought up The Simpsons episode is because I realized while doing this interview that everything I had ever written was the premise of the first thing I had ever written," he said. "All of my stories are about people trying hard not to grow up."
The episode is set to air January 11th at 8PM EST on Fox.
