Noise

S5, E4: When a physical indicates that Dave's blood pressure is on the rise, Jimmy worries about what all the stress at work is doing to him. To calm him down, Joe builds Dave a powerful white noise generator. And while skeptical at first, it doesn't take long for Dave to become addicted to the machine's soothing sounds. Meanwhile, as he and Lisa square off over her new on-air history segments, Max asks Beth to make Matthew to stop hating him. After Beth convinces Matthew to treat him with some tender loving care, Max upsets Lisa by going on the air with a history segment of his own. But when Lisa tries to complain, she finds that, because of the white noise machine's effect, Dave doesn't care. After Matthew fails to snap him out of it, Lisa intervenes by removing the generator from Dave's office. However, when he simply follows her around, Lisa's efforts only end up causing problems for everyone else, too. With Dave back in his office, Max irritates Lisa by interrupting her latest history moment with one of his own. When she complains, Jimmy realizes that Dave is too blissed out to handle the station's problems anymore. But, as he tries to intervene, Jimmy also falls under the machine's soothing spell. Finally, as Lisa strikes back on the air, Matthew exercises some motherly oversight of Max. And while Joe rescues Dave, he leaves Jimmy blissfully under the spell of the machine.
