\In the one-hour series finale of The Big Bang Theory, “The Change Constant” and “The Stockholm Syndrome,” while Sheldon (Jim Parsons) and Amy (Mayim Bialik) await big news, Penny (Kaley Cuoco) and Leonard (Johnny Galecki) try to keep a secret. It’s an emotional farewell for the actors who have worked together for the past 12 years.
Hours before the finale airs, Galecki posted a handful of photos from his last scene with Cuoco. The two are in a hotel room with a dessert tray. While Cuoco indulges with a spoon in her mouth, Galecki throws grapes at the photographer. He writes: “Throwing grapes at photographers is a favorite pastime.” The Big Bang Theory airs (for the last time) on Thursday, May 16 at 8 pm on CBS.
