"Big Bang Theory" actress Kaley Cuoco is going to have a hard time letting the show go — such a difficult time, in fact, the star says she plans to bring an item home from the set as a memento.

The 33-year-old, who plays Penny on the hit CBS sitcom, said the "special" prop will have a permanent place in her living room.

“It’s something that I love so much and I’ve looked at it for 12 years,” Cuoco told reporters during the Television Critics Association Winter Press Tour last week, according to People, revealing she plans to keep a poster of two robots wrestling.

The print has been hanging on the back of Leonard (Johnny Galecki) and Sheldon’s (Jim Parsons) door since they first started shooting the series back in September 2007, the magazine reports.

“It’s always in my eyeline from where I sit in the living room set, so I’m glad I’m going to put it in my own living room so I’ll see it forever,” Cuoco explained. “A lot of people want a lot of things, so I’ve already marked that one. It looks super random and weird, but it’s overly special to me.”

Warner Bros. Television, CBS and Chuck Lorre Productions first confirmed in August 2018 the long-running sitcom was coming to an "epic creative close" after Season 12. The news shocked both fans and cast members, including Cuoco, who reportedly said she "would have done 20 more years."

"I am, like, already losing it. These last few episodes have been really heartbreaking," a teary-eyed Cuoco told USA Today last week. "This sounds cheesy, but I've passed the 'Friends' stage for 20 years as an actor, and I always wanted our stage to be that way. I always thought that was so cool. This is really special."

The final episode of "The Big Bang Theory" will air in May 2019, but Cuoco already has a few projects in the works.

She's developing a limited series called "The Flight Attendant" with her new production company Yes, Norman Productions. She'll play the lead character in the show.

"Flight attendant Cassandra Bowden wakes in her hotel room hungover from the night before in Dubai with a dead body lying next to her," IMDB explains in a summary of the plot.

In addition to working on the series, Cuoco will go animated. The 33-year-old is set to executive produce and voice Harley Quinn in a new adult cartoon series based on the popular character.

"I’ve always loved animation. I did it years ago, and I haven’t been in the animation world in a while,” Cuoco told Entertainment Weekly. “[Harley Quinn] is so edgy, it’s obviously a very adult comedy, and with such a world-renowned character, it’s been a blast to record.”
