The chemistry between the TBBT cast was electric on-screen, but a new ‘leak’ from an upcoming, unauthorized biography on Kaley Cuoco suggests that not everything was laughter and ‘Bazinga!’ once the cameras stopped rolling. The drama is allegedly centered around the one thing every sitcom cast fights over: props.

According to a chapter titled “The Prop Heist,” Cuoco (who played Penny) was furious when she discovered her iconic apartment door, her favorite Cheesecake Factory uniform, and even the personalized name tag were ‘mysteriously absent’ after the series wrapped. The book claims that several cast members, unnamed but heavily hinted to be part of the ‘male core four,’ had ‘secured’ these sentimental items for themselves before the official auction.
“She felt the door belonged to Penny, and Penny belonged to her,” claims the source, describing a “tense phone call” where Cuoco demanded the return of the door for her personal memorabilia collection. The book suggests this caused a rift, with one actor reportedly sending her a sarcastic gift: a single, framed take-out menu from the Cheesecake Factory.
This revelation has TBBT fans playing detective, trying to figure out which ‘culprit’ has the famous Door 4A. While the official cast has remained silent, the rumor mill is churning. Was it the logical Leonard (Johnny Galecki), the sentimental Howard (Simon Helberg), or perhaps the socially awkward Raj (Kunal Nayyar)? The only one seemingly off the hook is Jim Parsons, who reportedly only took home one item: a single pair of Sheldon’s signature ‘flash’ socks.
