About the love of the heroes of the "Theory of the Big Explosion" to comics know every fan of the series. Moreover, the flash used to be extremely popular among them, because once they even dressed in Halloween into the same costumes, and Sheldon could often be seen in T-shirts with symbols of this character. But, as it turned out, in the TV series "Flash" also refers to a brilliant scientist.
Looks like Francisco Ramon, known as the superhero Waib, from the very beginning was a fan of Sheldon, because in the pilot series he wore a T-shirt with the inscription "Bazing!" - The corporate word of Jim Parsons.
Also, Francisco was seen in a T-shirt with the inscription "this is my place", and if the "Bazing" can also be reference to the game "Stone-scissors-paper-paper-spock paper", then only Cooper said about the favorite place on the sofa.
Since both serials were created by Warner Bros. Television, the logic is that Flash and the "Theory of the Big Bang" echoes each other, definitely there. And most importantly, this discovery truly delighted Sheldon fans, who had to say goodbye to his favorite hero after the end of the series last year.
