Sitcoms had different types of laugh tracks edited onto their soundtracks, depending on style. Outlandish or fantasy shows, like "Bewitched", "The Munsters", "I Dream of Jeannie" and "The Beverly Hillbillies", were virtual showcases of Douglass's editing skill. The more outlandish the show, the more invasive the laugh track. Conversely, subdued programs, like "The Andy Griffith Show", "The Brady Bunch" and "My Three Sons", had more modulated laughter. Certain shows, like "Get Smart", featured a laugh track that became more invasive as the series progressed, while shows like "M*A*S*H" toned down the laughter as the series became more dramatic (it was entirely absent during operating room scenes).
