A short clip from The Big Bang Theory theme song, with its famous opening line about the start of everything, used as an intro or punchline in edits and memes.
This is a short, upbeat snippet from the opening theme of The Big Bang Theory, built around the catchy line that everything started with the big bang. A bright, fast guitar riff drives it forward while the vocal lands with a playful shout, giving the clip a burst of nerdy energy in just a couple of seconds. Because the show ran for many years, the melody feels instantly familiar even to people who only half remember it, and hearing it sets a light, geeky, sitcom mood. It works best as a jolt of recognition, turning an ordinary moment into something that feels like the start of a clever, science-flavoured joke.
The clip comes from the opening theme of The Big Bang Theory, the American sitcom that ran from 2007 to 2019. Its theme, performed by Barenaked Ladies, races through the history of the universe in under a minute, ending each run with the idea that everything started with the big bang. The song became inseparable from Sheldon, Leonard and their friends, and the opening bars are now a shorthand for geek culture itself. Short excerpts circulate on soundboards and in short-form videos, where a couple of seconds is enough to signal a nerdy joke or a clever twist.
