Homer test drives - and destroys - a new electric car so that he can get a free gift, which turns out to be free tickets to a preview screening of the new Mel Gibson film, a remake of "Mr. Smith Goes to Washington". The audience members are given comment cards to fill, so that the filmmakers can change the film based on the audiences' reactions. The film is enjoyed by everyone but Homer. During the screening, Gibson, having come to the test screening unannounced, is assured by the producers that the film is wonderful, but while reading the comment cards after the movie, he is certain that everyone loves him too much to tell him how to improve the film. When he reads Homer's comments, partially inspired by him seeing Gibson flirting with Marge, he thinks that Homer was the only person brave enough to tell him the truth.
