For 12 seasons, The Big Bang Theory left viewers laughing, crying, and — if we're being honest — a little confused by all the science talk. Since the series' 2007 debut through its finale in 2019, the quirky bunch that included Sheldon Cooper, Leonard Hofstadter, and Penny (we never did learn her last name, did we?) had quite a few adventures. From hikes up apartment stairs to detailed Comic Con costumes and too many takeout containers to count, the sitcom remains iconic to the fans who know and love the gang's adorably nerdy world.
