CLIPS on Instagram: "😂 Interesting fact: In The Big Bang Theory (2007-2019), the whiteboards filled with equations in Sheldon and Leonard’s apartment weren’t random scribbles. A real UCLA physicist updated them for every episode, so the math you see on screen is actually accurate… even if the characters arguing about it definitely weren’t."

the big bang theory fans on Instagram: "When Sheldon labels everything in the apartment, even the label maker, you know we're deep in the roommate agreement. Vintage whiteboards, knock-knock rituals, and a dash of Bazinga never get old Let’s go: stick with @the.big.bang.th.ig for memes — 24/7 . . . . . . #thebigbangtheory #sheldoncooper #tbbt #bazinga #bigbangtheoryfan"
