Stumpers! is a game show hosted by Password emcee Allen Ludden that aired on NBC from October 4 to December 31, 1976. Lin Bolen, former head of NBC Daytime Programming, developed the show. Bill Armstrong was the program's regular announcer, with Charlie O'Donnell filling in for several episodes. The show featured game play similar to Password, with two teams attempting to guess the subject of puzzles based on clues provided by their opponents. The series premiered and ended on the same dates as 50 Grand Slam, which immediately followed Stumpers! on the NBC schedule and was hosted by Ludden's good friend Tom Kennedy, who made a walk-on appearance during the closing segment of the Stumpers! premiere.
