3 The Fuzzyboots Corollary
Leonard is depressed to learn that Penny is dating someone. As a result, encouraged by his friends and fellow scientists, Leonard actually summons the nerve to ask a woman out on a date. SARA GILBERT ("Roseanne") guest stars as Leslie.
4 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 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 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 The Dumpling Paradox
When Wolowitz seduces Penny's friend and ends up sleeping with her in Penny's apartment, Penny sleeps on Leonard and Sheldon's couch.

Koothrappali becomes overwhelmed when his parents arrange a blind date for him, but he discovers he actually can talk to a member of the opposite sex after a few drinks. However, complications arise when his beautiful date shows more interest in Sheldon.

When Leonard and Sheldon meet a 15-year-old physics prodigy, Sheldon is distraught that this boy genius is younger and smarter. In an attempt to restore a sense of purpose, the boys come up with a solution to derail the young prodigy's research.
13 The Bat Jar Conjecture

And since he was as dumb as a box of rocks, I hated most of the stuff he liked. While he'd laugh at Leonard and Sheldon's first season antics I was wondering when more reruns of Star Trek would be on and how my guild in World of Warcraft was fairing on their latest raid. You know, important stuff.

First off if this show offends you GOOD. You are weak person don't have children because we don't need anymore fingers in the pudding. You forgot how to enjoy yourself and laugh, at that point your life is not worth living and you should check out early. No body likes people who cry about everything or only looks for the negative just watch CNN because you cant think for yourself. Your not clever its not a new thing to wine about stupid things to think your edgy and hip. NO BODY CARES.. with that said this is a good show.

This show is funny and clever with all the characters showing development in there personality's . I don't know how the reviewer Izy comes to the conclusion that this show is politically incorrect considering the spectrum of the characters background and the balance of casts sexuality and religious beliefs or lack of in some cases, two gay,one Jew,one Hindu, one atheist, a couple of agnostics, one over the top christian. I am sure I have missed some characters (sorry).love the show may it continue forever
