Full House, a beloved sitcom of the 1980s and 1990s, had fans scratching their heads over an odd detail - the presence of two staircases in the main characters' home. With one in the living room and the other in the kitchen, they both led to the same upstairs spot, yet only one was visible from upstairs. The confusing layout sparked interesting theories, but none could explain the strange design. Despite the show's enduring popularity, the dual staircases remained a puzzling plot hole that added an extra layer of mystery and suspense to the iconic Tanner family home.
