D'oh-in' in the Wind

"D'oh-in' in the Wind" is the sixth episode of the tenth season of the American animated television series The Simpsons. It first aired on Fox in the United States on November 15, 1998. In the episode, Homer Simpson travels to a farm owned by Seth and Munchie, two aged hippies who were friends with Homer's mother. After finding out his middle name is "Jay", Homer is drawn to the carefree lifestyle of hippies, and decides to become one himself.

The episode was written by Donick Cary and directed by Mark Kirkland, who was going through a divorce at the time of its production. Due to personal circumstances, Kirkland assigned his assistant director, Matthew Nastuk, to take over the directing duties for a couple of scenes in the episode. However, after Nastuk had directed a scene, Kirkland felt better and returned to direct the rest of the episode. The episode features the revelation of Homer's middle name, "Jay", which is a tribute to characters from The Rocky and Bullwinkle Show who got their middle initial from Jay Ward.

The episode features comic actors George Carlin as Munchie and Martin Mull as Seth. Carlin was suggested by Simpsons writer Ron Hauge, who "really wanted to meet him", although he did not attend the recording session with Carlin and Mull.

In its original broadcast, the episode was seen by approximately 8.4 million viewers. Following the tenth season's home release on August 7, 2007, "D'oh-in' in the Wind" received mixed reviews from critics.
