Because details of what’s happening on-set are super secretive, each of the actors had to get super creative in their reveals. “Starting Season 11 of @BigBangTheory today! So excited!,” Mayim, 41, captioned a photo of herself holding the new script on Twitter. Though the script is clearly visible, Mayim blocked out every other detail with her arm. Kunal — who plays Raj Koothrappali on the series — covered his script details with a pen and Kaley gave a nod to the intelligent characters on the show by covering her script particulars with a Rubik’s Cube.

This year marks Big Bang Theory‘s 10-year anniversary, though it’s been on for 11 seasons. The first episode in Season 11 will be Big Bang Theory‘s 232nd episode, a landmark number for CBS.

When did the Big Bang Theory debut?

The nerdy comedy first debuted in 2007 and wasn’t originally envisioned by show creators as the “family sitcom” that it has since become. “A show about brilliant minds was what we led with,” creator Chuck Lorre told The Hollywood Reporter. “We never said the word ‘nerd’ or ‘geek’; those words came later; they were attached to the show. We were more interested in these guys that were crazy smart and their inability to move through the world that the rest of us take for granted.”
