It's always fun to find a few easter eggs hidden in our favorite movies and tv shows, and The Big Bang Theory has revealed a few hidden in the hit CBS sitcom on the network's website.

One of the fun surprises has to do with Penny's (Kaley Cuoco) former apartment, notably the decor used to personalize the space.

Set decorator Ann Shea told CBS that the character is "very girlie," so Shea wanted to incorporate lots of bright colors into the space since she couldn't paint the walls.

Along with bright colors, Penny's personality was also put on display with photographs on her fridge, which actually feature Cuoco and crew members from the show. The snaps include Cuoco with crew and cast, including Amy (Mayim Bialik), Bernadette (Melissa Rauch), and Leonard (Johnny Galecki).

Since Penny no longer lives in her apartment, the fridge looks markedly different now that the space is inhabited by Sheldon (Jim Parsons) and Amy, but some of Penny's photos have crossed the hall to the apartment she now shares with Leonard, as Redbook shares.

Also revealed? Every equation written on a whiteboard in the show is actually a real scientific equation.
