Stick around after The Big Bang Theory's series finale to watch the show say goodbye to itself.

CBS announced Monday that after the Big Bang finale on May 16, the network will air "Unraveling the Mystery: A Big Bang Farewell," a half-hour special in which stars Johnny Galecki and Kaley Cuoco take viewers behind the scenes of the longest-running multi-camera comedy series in television history. In the special, Galecki and Cuoco will take fans on a trip down memory lane, sharing backstage secrets and their favorite memories from their 12 years on the show, as well as leading a tour of the show's iconic sets — if you've ever wanted to know what's behind the apartment building's broken elevator door, maybe tune in for this.

The retrospective will air Thursday, May 16 at 9:30/8:30c, after The Big Bang Theory's one-hour series finale at 8/7c and Young Sheldon's Season 2 finale at 9/8c.

The Big Bang Theory airs Thursdays at 8/7c on CBS. It's available to stream on CBS All Access.
