The Big Bang Theory is well known for being stuffed full of scientific and pop culture references—but just how many of these references are true? Let’s look at four, admittedly nitpicky, inaccuracies in The Big Bang Theory.
Sheldon doesn’t know the right “Gremlins” instructions
In the fourth episode of season 3–the Pirate Solution–Sheldon makes a remark about the popular 80s film, Gremlins. He says that the film “baffles” him because the entire premise is based on forgetting simple rules of care. “Just don’t feed gremlins after midnight!” However, in the film, the rule is not to feed Mogwais after midnight; gremlins mutate from Mogwais if they are fed after midnight.
Leonard mislabels yogurt
Towards the beginning of The Bad Fish Paradigm (Season 2, episode 1) Leonard explains to another character eating some store-bought yogurt that what they’re eating is technically not real yogurt, because it “doesn’t have enough live active acidophilus cultures.” However, according to the USDA standards for classifying food products as yogurt, only two other types of starter cultures–and not live active acidophilus cultures–are required. While live active acidophilus cultures can be present in yogurt, they are not used to determine whether or not something can be classified as yogurt.
The wrong Bollywood movie
During one scene in The Bad Fish Paradigm (season 2, episode 1) both Sheldon and Raj are watching TV together inside Raj’s apartment. The audience isn’t shown what is on the screen, but Indian-style pop music is heard in the background. Sheldon asks if the woman in the film is Aishwarya Rai, and Raj says yes; he and Sheldon then argue about whether or not the actress is Rai or Madhuri Dixit. However, the music used during the scene is from a Bollywood movie called Kaho Na Pyari Hai—which has neither Dixit nor Rai in the cast.
Sheldon is no match for the Reinheitsgebot
In the second episode of season 2, The Codpiece Topology, Sheldon is discussing the historical accuracy of drinking mead during the year 1487. He states that the Reinheitsgebot (a centuries-old law) would have made mead unavailable to most of the public. However, the law as Sheldon described it was not fully introduced 1516, well after 1487. This particular law also dealt with the prices and ingredients of beer, and not other drinks such as mead; therefore, mead would not have been affected.
