S15E15 Co-Dependent's Day
After seeing lousy film 'Cosmic Wars', which they were looking forward to for a long time, Bart and Lisa want to let the director know the new movie sucked. A complaint letter gets ignored and Bart and Lisa want to personally speak to the director. Because he lives in the neighborhood of a winery Homer and Marge agree. While Bart and Lisa talk to the director, Homer and Marge discover alcohol brings them together and make a habit of drinking wine and getting drunk together.
