Summary

The Big Bang Theory Season 1

Leonard and Sheldon are brilliant physicists, the kind of "beautiful minds" that understand how the universe works. But none of that genius helps them interact with people, especially women. All this begins to change when a free-spirited beauty named Penny moves in next door. 

Sheldon, Leonard's roommate, is quite content spending his nights playing Klingon Boggle with their socially dysfunctional friends, fellow Caltech scientists Wolowitz and Koothrappali. However, Leonard sees in Penny a whole new universe of possibilities... including love.

Episode guide

  1. 01 - Pilot

    Two brainy best friends, Leonard (series star JOHNNY GALECKI) and Sheldon (series star JIM PARSONS), could tell you anything you want to know about quantum physics - but when it comes to dealing with everyday life here on Earth, they're lost in the cosmos. Leonard and Sheldon are brilliant physicists, the kind of "beautiful minds" that understand how the universe works. But none of that genius helps them interact with people, especially women. All this begins to change when a free-spirited beauty named Penny (series star KALEY CUOCO) moves in next door. Sheldon, Leonard's roommate, is quite content spending his nights playing Klingon Boggle with their socially dysfunctional friends, fellow Caltech scientists Wolowitz (series star SIMON HELBERG) and Koothrappali (series star KUNAL NAYYAR). However, Leonard sees in Penny a whole new universe of possibilities ... including love.

  4. 04 - The Luminous Fish Effect

    After being fired from his job, Sheldon attempts to explore the "dreadful" life beyond physics. But his initial thrill of shopping with Penny devolves over time to him weaving ponchos as a shut-in, forcing Leonard to call on Sheldon's mother, Mary (LAURIE METCALF - "Roseanne").

  5. 05 - The Hamburger Postulate

    After sensing that his pursuit of Penny isn't going anywhere, Leonard agrees to an unexpected sexual encounter with fellow scientist Leslie Winkle (recurring guest star SARA GILBERT). The one-night stand throws Leonard and Sheldon deep into uncharted social waters.

  6. 06 - The Middle Earth Paradigm

    The socially stunted guys are nervous when Penny invites them to a party she's hosting. But they are ecstatic to find out that it's a Halloween party and enthusiastically don their respective nerdy costumes, which unfortunately fail to impress Penny's brutish ex-boyfriend. Afterwards, Koothrappali experiences the unexpected with a partygoer, Cheryl (ERIN ALLIN).

  7. 07 - The Dumpling Paradox

    When Wolowitz seduces Penny's friend and ends up having sex with her in Penny's apartment, Penny sleeps on Leonard and Sheldon's couch.
