The term bellows is used by extension for a flexible bag whose volume can be changed by compression or expansion, but not used to deliver air. For example, the light-tight (but not airtight) bag allowing the distance between the lens and film of a folding photographic camera to be varied is called a bellows.
What NFL has lost the Super Bowl the most? The Buffalo Bills, the Denver Broncos, the Minnesota Vikings, and the New England Patriots have all lost four Super Bowls. Edit
Date: 1990-1993. Set by: Buffalo Bills. We're not sure which is a more incredible achievement, the fact that the Bills managed to make four straight Super Bowl appearances, or the fact that they failed to win a the big game. Arguably one of the weirdest records in NFL history, because we're not sure whether to applaud or shake our heads. The only team that's come close to matching this were the Dolphins. The 'Fins made back-to-back-to-back appearances in Super Bowls six through eight, and even managed to win two.
