In the pantheon of modern sitcoms, few shows have achieved the cultural saturation and long-running success of The Big Bang Theory. Before the catchphrases ("Bazinga!"), before the celebrity cameos (Hawking, Whedon, and Wil Wheaton), and before the Emmys, there was a humble, low-rated pilot, a network reshoot, and a season of television that felt more like an indie indie-comedy than a ratings juggernaut. This article takes an in-depth look at The Big Bang Theory S01, the 17-episode foundation that introduced the world to Leonard, Sheldon, Penny, Howard, and Raj.
This episode is a fan-favorite for showing the extreme consequences of Sheldon's rigidity. After getting fired from the university for correcting his boss, Sheldon retreats into a world of bizarre hobbies: weaving loom scarves, cloning fish, and sitting in a penny-filled bathtub to "feel the sensation of poverty." Leonard, desperate, summons Sheldon's Texan mother (the incredible Laurie Metcalf, in her first appearance). It sets the template for "Sheldon vs. The Real World."
Here is a chronological breakdown of every episode in Big Bang Theory S01. Note the "Pilot" is technically Episode 1.
