The Einstein Approximation - S3-E14
Revealing mistake: In the scene where Sheldon visits Leonard and Penny in bed, towards the end of the scene, Leonard turns off the light. As he does, if you look carefully, you can see that the light turns off before he hits the switch.
The Excelsior Acquisition - S3-E16
Plot hole: In Series 1, Episode 7, "The Dumpling Paradox, " Sheldon makes an oblique reference to his financial status: "Frankly, if I could afford the rent, I'd ask you [Leonard] to leave, " meaning he cannot pay the rent on his two bedroom apartment by himself - not that he doesn't want to, he can't. However, in "The Execlsior Acquisition, " we find that he does not even cash his pay cheques. He doesn't even deposit them into a bank account - he leaves them in a drawer in his desk. In Series 2 Episode 14 "The Financial Permeability", he lends Penny a large amount of money from a huge bankroll he just happens to have lying about - again, without cashing his pay cheques! He is obviously independently wealthy. Either he doesn't have enough money to afford the rent or he has enough to work without being paid while practically giving large amounts of cash away. Can't be both.
Suggested correction: He doesn't say he can't financially afford the rent; he may have meant emotionally or functionally. He may feel that he needs the social support from living with other people. He couldn't afford not to have them with him.
What nonsense. He says, "Frankly, if I could afford the rent, I'd ask you to leave." If I could afford the rent – he is talking about money, not some vague, waffly jibber-jabber about emotional support.
He definitely meant emotionally. I just watched a random clip on YouTube from when Penny and Leonard were wanting to move in together and Sheldon lost it (and they mention it's not the first time). Saying he couldn't afford it is his excuse because he wouldn't admit (at that time) that he would be devastated.
The Big Bran Hypothesis - S1-E2
Sheldon: Oh Gravity, thou art a heartless bitch.
Trivia: During Season 3, the producers learned of a show called "The Theorists" in the country of Belarus that was a copy of this show. A lawsuit for copyright infringement would have been pointless since the production company for "The Theorists" was owned by the Belarus government. A lawsuit, however, was not needed because when the actors and actresses found out the show was a rip-off this one, they promptly quit and "The Theorists" was cancelled.
The Euclid Alternative - S2-E5
Question: Though it comes up in other episodes as well, this one is focused on Sheldon needing a ride everywhere he goes because he can't drive, not to mention his not being welcome on the bus. Of course, this story element would be nonexistent if there was a simple answer, but it does beg the question: Does Pasadena not have taxicabs?
