Leonard Hofstadter and Sheldon Cooper are both brilliant physicists working at Cal Tech in Pasadena, California. They are colleagues, best friends, and roommates, although in all capacities their relationship is always tested primarily by Sheldon's regimented, deeply eccentric, and non-conventional ways. They are also friends with their Cal Tech colleagues mechanical engineer Howard Wolowitz and astrophysicist Rajesh Koothrappali. The foursome spend their time working on their individual work projects, playing video games, watching science-fiction movies, or reading comic books. As they are self-professed nerds, all have little or no luck with women. When Penny, a pretty woman and an aspiring actress from Omaha, moves into the apartment across the hall from Leonard and Sheldon's, Leonard has another aspiration in life, namely to get Penny to be his girlfriend.

There are 16 mailboxes but the building has only ten apartments - two on each of the five floors. Since all apartments are numbered by the floor plus a letter (the guys live in 4A, Penny in 4B) it is not possible that there is a never seen third apartment on each floor. First off, there are no apartments shown on the first floor. Secondly, it is possible that there are four apartments on each floor (two being unseen), and furthermore there is at least one more floor above the one Sheldon, Leonard, Penny, and later Amy live on (since the hallway/stairs/elevator scene is recycled for each floor).

Penny: So, what do you say Sheldon, are we your X-Men?
Sheldon: No. The X-Men were named after the X in Charles Xavier. Since I am Sheldon Cooper, you will be my C-Men.
Howard Wolowitz: [as Sheldon walks away] Oh, that's not a good name.

User Reviews

The first fiew seasons will always be the best
3 January 2021 | by Adam-09265See all my reviews

I miss the show when it was about nerdy men nerding over science experiments and awkward women encounters. It then after about five seasons turned into a 'Please the Wife- Soap Opera'.

I hate Bernadette's character and how much she belittles Howard like a strict mother, constantly telling him what to do and making him a puppet to fill her needs. Howard has always been a funny character but being in that relationship made his humour all caged.

Sheldon reminded me of Spock, an awkward intellect who's spot-on logic and obsessive compulsive disorder made it an inspiration even at the weirdest of moments. Although throughout the series you notice Sheldon starts to slowly lose his Sheldon'ness and starts to become more human in a sense. Which made it slightly displeasing to what we loved Sheldon for in the first place.

Penny being the stereotypical sex driven blonde was ok, her beauty made the boys more awkward like nerds would be. Sheldon's intelligence overpowering hers is what also made it funny for social awkardness, him constantly correcting her and her replying sarcasticly showed the difference between the two. Her and Leonard's relationship was not a problem, but when they all had relationships, it became an occurring thing to have at least one relationship problem in an episode and it made the viewing cringy.

The show still has a decent episode everynow and then but it's not as funny as the first few seasons.
