Is this an episode title from The Big Bang Theory? (Or is it made up?) TV quiz
Ever since it first hit our screens in 2007, ‘The Big Bang Theory’ has left a big mark on popular culture. With its unique blend of humour, science, and heart, the show quickly became a favourite among audiences around the world. Centred around a group of intellectually gifted yet socially awkward friends – Sheldon Cooper (Jim Parsons), Leonard Hofstadter (Johnny Galecki), Howard Wolowitz (Simon Helberg), Raj Koothrappali (Kunal Nayyar), and the socially savvy aspiring actress Penny (Kaley Cuoco) – the show offers laughs, friendship, and a sprinkle of scientific jargon in every episode. In short, it’s a classic comedy in the mould of shows like Friends and Parks and Recreation.
One distinctive feature of ‘The Big Bang Theory’ is the intriguing and often humorous episode titles, usually based on a scientific principle or theory and almost always starting with “The.” However, with 279 episodes spread over 12 seasons, it can be tough to remember every single title. So, we’ve compiled a list of 20 episode titles – some real, some made up – for you to identify.
Your task is to decide whether each title was really used in ‘The Big Bang Theory’ or if we’ve cleverly fabricated it. The correct answers, including the season and episode numbers for the real ones, are listed at the end.
