After the series finale, the entire cast of The Big Bang Theory appeared on The Late Show with Stephen Colbert, where they announced their characters' iconic costumes would be heading to the Smithsonian National Museum of American History.
The historic Washington museum's entertainment section will now feature an exhibit that includes Sheldon Cooper's iconic Flash T-shirt and Leonard Hofstadter's Recycle signature tee, as well as costumes worn by Howard, Raj, Penny, Bernadette and Amy.
Of course, while The Big Bang Theory may be over, the world it created lives on in Young Sheldon. The flashback spinoff features the voice work of Jim Parsons, who offers glimpses of Sheldon's future through the lens of his past. The series just concluded its second season, but it will return for Season 3 this fall.
The Big Bang Theory concluded its 12-season run with an hour-long series finale on May 16. The series stars Jim Parsons, Johnny Galecki, Kaley Cuoco, Mayim Bialik, Kunal Nayyar, Simon Helberg and Melissa Rauch.
