In season nine, episode seven, The Spock Resonance, Sheldon is asked to take part in a Star Trek documentary by Wil Wheaton.
Sheldon is overjoyed to have been asked to participate, especially when Wil reveals Bill Nye’s son will be on hand to help.
During the interview, Adam asks Sheldon: “Do you have any Spock collectables?”
Sheldon said: “I have many. My most treasured is an autographed napkin given to me by my very thoughtful friend Penny.”
While Penny and Leonard process what the camera may have caught them doing, a problem lies with when Sheldon said it was installed.
In 2012, the sixth season of Big Bang Theory premiered with The Date Night Variable.
During the episode, Leonard and Penny are working on their relationship and gather at Leonard’s to watch sports.
However, in the background, there was no Aquaman on display.
In fact, the Aquaman character doesn’t appear in its spot throughout the sixth season.
The argument could be made that the Aquaman camera was installed by Sheldon and initially placed elsewhere.
However, the fact he had been supposedly “protecting their home” since 2012 suggest surely he would’ve needed to be in plain sight.
As for the wall and floor safes, it is feasible they existed in 2012 as the whiteboard is there.
The Big Bang Theory is available to stream on Netflix UK now.
