The Big Bang Theory cast, a household of brilliant but socially akward scientists. Working together at Caltech, Sheldon Cooper and Leonard Hofstader are physicists, Howard Wolowitz it's an aerospace engineer and Raj Koothrappali an astrophysicist. Barely leaving the living room unless they are going to the Lab, their remarcable lifes and years of friendship are full of games, theories and experiments. #BigBangTheory #BigBang #Geek #HelloSimmer
