Season 1: 2007-08

Physicists Dr. Leonard Hofstadter and Dr. Sheldon Cooper get their lives shaken up when an attractive young aspiring actress from Omaha, Nebraska named Penny moves in to the apartment across the hall from theirs. Leonard begins to become hopelessly enamored of Penny, while she feels only platonic affection for him; as a result, she finds herself putting up with his closest and ever-present friends: his roommate, Sheldon, who appears borderline obsessive-compulsive; engineering whiz Howard Wolowitz, a desperately sex-crazed mama's boy who thinks that his 1970s-style clothing and hairstyle give him an air of cool hipness; and Dr. Rajesh "Raj" Koothrappali, who will not speak to her, as he is too shy to talk to girls, unless intoxicated, where he becomes a smooth talking yet highly overly aggressive womanizing flirt.
.During Season One: Sheldon loses his job for insulting his new boss, finds his ego bruised by a child prodigy, and finds himself unable to bear being part of a lie that Leonard has told—always attacking the world with a relentless need to assert his supremacy; Rajesh first learns that he can talk to girls, but only when he's drunk; and Penny and Leonard go out in the final episode.^ And finally in the season finale, The Tangerine Factor, after Penny breaks up with her new guy, she agrees to go out on a date with Leonard.

Sheldon and Koothrappali attend a university mixer, with Sheldon as Raj's wingman. .Sheldon only went because Raj bribed him with a Green Lantern lantern, which Sheldon brought with him to the mixer.^ First, he had to use his guitar, because the judges more or less told him so when he went though the last time without it.

.They meet Abby (Danica McKellar), who takes a liking to Raj, and her friend Martha (Jen Drohan), who tries to connect with Sheldon.^ Trouble is, they were each trying clumsily to hide the real story, which is that Joanna Pacitti was sent packing for having too many insider connections for comfort.

^ (If we meet our friends at noon, then it takes four numbers to specify the space and time of the meeting.

.They end up playing Rock Band at Sheldon's place.^ While playing shows in England in 1969, the band discovered they were being mistaken for another English group named Earth, and decided to change their name again.

^ Barton and the band didn't quite synch up, but we don't know how much (or how little) practice they had beforehand.

For a second date, Raj bribes Sheldon with his pair of Hulk hands, signed by Stan Lee. .After Sheldon announces that he is going to bed, Martha asks if she can come into his room to avoid Raj and Abby, who are "getting busy."^ "Three days before we were due to go into the studio, Ozzy wanted to come back to the band," Iommi explained.

^ This type of fight raises morale on the team of the player who wins, and often gets the home crowd into the game as well.

Sheldon obliges but immediately leaves to sleep in Leonard's room instead, leaving Martha alone. Meanwhile, Leonard and Penny go on a double date with Howard and Bernadette, and Leonard is upset to discover that Penny believes in psychics. Later, Howard shows Leonard that if he wants to be able to ever be in a relationship, he'll have to accept that people will have differing beliefs. Leonard apologizes to Penny and agrees to visit her psychic, while she declines to read a book debunking psychics.

When their apartment is robbed and their TV, video games, and computers are stolen, Leonard and Sheldon turn to Howard to create a state-of-the-art security system, which includes an electrified net over the door. Sheldon gets caught in that net and decides he needs to leave Pasadena. He gets online and rules out several cities for different reasons, including Enid, Oklahoma, and Boone, North Carolina. .He rules out all of Nebraska because Penny is from there.^ "Lost" ABC via DVR For a week or so there, I thought I had the endgame for "Lost" all mapped out in my head, but now I don't know which way is up again.

^ We would laugh at them, because, of course, we know there is no "force" at all, just the rippling of the water.

.One attempt in a mall ballpit has Leonard jump in and try to get Sheldon out as he pops in and out, shouting "Bazinga!". He then decides that he needs a menial job to think better because Albert Einstein came up with the Theory of Relativity while working a menial job at the Swiss Patent Office.^ Matt Giraud Poor, dumb Matt just can't get out of his own way, which is too bad because I think he's genuinely a better singer than Kris Allen or Danny Gokey -- he just keeps trying to force a signature moment with songs that are too big, too distinctive, or in this case, too sexy for him.

^ But to calculate if these quantum corrections are intense enough to close the Einstein-Rosen bridge, one necessarily needs a unified field theory which includes both Einstein's theory of gravity as well as the quantum theory of radiation.

^ "It was something we had to really wring out of ourselves, but I think that's why it works", he said.

.Since the American patent office is in Washington DC, and he doesn't want to move out of Pasadena, he interviews for any menial job with the County of Los Angeles, where he is interviewed by a woman played by Yeardley Smith.^ Now that all former members of the group had moved on, Münzing and Anzilotti recruited Washington DC-born singer Summer to front the act for the third album.

^ Think about relativity: Einstein worked out the math before anyone was able to see his predictions in reality.

Later, Penny talks to Stuart and gets Mr. Lee's address, and she and Sheldon show up there unnanounced.
