According to a Center For Media Studies report released Monday, the average age of wacky TV-sitcom neighbors has steadily declined over the past half-century. 'In the '50s, during the days of Ed Norton and Fred and Ethel Mertz, the median age was a mature 53,' the report read. 'By the late '70s and early '80s, with the likes of Larry on Three's Company, Monroe on Too Close For Comfort, and Lenny and Squiggy on Laverne & Shirley, the average had dropped to 36. Today, the wacky-neighbor landscape is dominated by twentysomethings, typified by Jack on Will & Grace and all the friends on Friends.' At the present rate, the report added, wacky TV neighbors will primarily be toddlers by 2015.
