Known for its heartwarming family-centric plot, the iconic TV show Full House has quite a few inconsistencies and plot holes despite its immense popularity.  For example, the physical layout of the Tanner's house – described as including an attic and two sets of stairs leading to the same upstairs area – doesn't align with the building's external appearance, where no attic is visible. There were also some gaps in character narratives, specifically Uncle Jesse's high school education, and the age and existence of Kimmy's siblings.  The inconsistency about Jesse's graduation was shown when he admits to dropping out in season 6, despite earlier indicating his graduation in season 4.  Meanwhile, Kimmy Gibbler's siblings seemed to change every time she mentioned them, going from being an only child to suddenly having longer a list of siblings.
