Boston

S5, E9: As Dave prepares an inspirational videotape as a favor to his old high school English teacher, Max points out that Lisa has a speech impediment. And it's only after he offers to help correct it that Lisa discovers everyone else agrees he's right. While helping tape Dave's speech, Joe listens as he encourages Mr. Thernstrom's students to set high goals. Pointing to his own disastrous experience in college, Joe asks Dave to not repeat his mistakes and to tell the students to aim low. Meanwhile, a suspected case of Carpal Tunnel Syndrome sidelines Beth. As he works on Lisa's speech problem, it doesn't take long for Max's efforts to bring back a working class Boston accent that she's successfully hidden for many years. Though her colleagues at the radio station have a field day making fun of her, Lisa proudly embraces her working class background. But once Jimmy hears her on the air, he decides to take matters into his own hands. Meanwhile, when he overhears Dave recommend that the students follow their hearts, Jimmy suggests otherwise. As Beth take Joe aside to admit she's faking her injuries in order to cover up an embarrassing nail polish job, Max tells Dave not to pay any attention to everyone's suggestions about the tape. Yet, after defending his co-workers, Dave then sets out to finish his speech while Jimmy works on Lisa. Finally, Dave completes the speech and sends it off, unaware that Mr. Thernstrom is really in the hospital for the mentally ill.
