Kaley Cuoco shares footage of 'Big Bang Theory' cast's final flash mob: 'One

Kaley Cuoco, Jim Parsons, Mayim Bialik and many more of The Big Bang Theory cast and crew pulled off an epic flash mob on the set of the hit CBS show this week. The surprise dance sequence has become a tradition after Cuoco came up with the idea years ago, although this one was particularly sentimental given it was their last. The acclaimed series is currently in its final season.

The 33-year-old actress gave fans a glimpse of the mayhem, declaring it “one of my favorite moments in 12 years.”

Even creator Chuck Lorre FaceTimed in to watch the dance, which was set to the tune of the Backstreet Boys hit “Larger Than Life.”

Cuoco said the song was chosen because it’s one that “thanks the fans.” Her sister, Bri Cuoco, helped choreograph the ditty. The actress, who plays Penny on TBBT, shared lots of behind-the-scenes videos and thanked the “crew who rehearsed for months and listened to me yap on and on about this endlessly!” (Click to scroll through for more.)

Members of the live audience, which included some of Cuoco’s family and friends, were treated to catching the number in person.

An on-set flash mob was Cuoco’s idea years ago as a thank-you to the showrunners and fans. Past songs have included hits like Carly Rae Jepsen’s “Call Me Maybe” and Bruno Mars’s “Uptown Funk.”
