The Holographic Excitation - S6-E5

Trivia: In this episode, Sheldon and Amy are trying to decide on couples' themed Halloween costumes. Sheldon is standing in front of the dry erase board. There are 2 columns written on the board. One named "Couples I Like" and the other "Couples You Like." Under the "Couples You Like" column, one of the couples is Blossom and Joey. Blossom is the name of the television character played by Mayim Bialik in the 90s and Joey was one of her brothers.

Trivia: Amy's apartment number is 314, ie. Pi (well, a variation - 3.14...). Very fitting.

The Bat Jar Conjecture - S1-E13

Trivia: When Leonard, Howard and Raj are contemplating who to have as the fourth member of their Physics Bowl team, Raj says, "You know who's apparently very smart is the girl who played TV's 'Blossom'. She got a Ph.d in Neuroscience or something." The girl he's referring to is actress Mayim Bialik, who plays Amy Farrah Fowler in later episodes of The Big Bang Theory. Interestingly, she is the only recurring cast member on the show that actually does have a Ph.d in real life.

The Excelsior Acquisition - S3-E16

Trivia: Raj's question about why so many of Stan Lee's characters' first and last names begin with the same initial (Peter Parker, Reed Richards, Bruce Banner, etc.) has been answered by Lee in interviews before: He has a bad memory for names, so if he can remember one of their names, he knows the other starts with the same letter.

The Recollection Dissipation - S10-E20

Trivia: When Amy sings "Soft Kitty" in German she more or less translates it literally. The German dubbed version of the show uses completely different lyrics for its rendition instead of just translating the original version.

Trivia: When Penny becomes a bartender, it was because Kaley broke her leg horse riding and they had to keep filming, so she kept the cast hidden behind the bar.

Trivia: You don't have to be a big The Big Bang Theory fan to know that Sheldon has his spot on the couch, but did you notice that other characters also sit in 90% of scenes on the one spot. Leonard is always on the sofa left to Sheldon, Penny is almost always on the sofa across Sheldon, Howard is always next to Sheldon on the couch (except in situations when Amy or Bernadette sit between him and Sheldon), and Raj is always on the left side of the couch (viewers' left), or on the floor.

The Countdown Reflection - S5-E24

Factual error: There is not a snowball's chance of Howard becoming an astronaut. He suffers from cardiac arrhythmia, something about which he is completely open. "Transient" or not this is easily detectable by a simple electrocardiogram, which is a fundamental part of the many medical examinations a potential astronaut will have to pass. He wouldn't even be allowed to start basic training. Note also that during his basic training he shows signs of severe stress and trauma which would inevitably trigger a cardiac episode. Even if it didn't the fact that he was falling apart at the seams would have him removed from the programme for his own good.

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?

MFWills

Chosen answer: It does. The variable cleanliness of the cab and the habit of taxi drivers to engage customers in small talk would be too much for Sheldon to handle, and not an option for him.

Captain Defenestrator

Answer: Sheldon DID finally use a taxi when going to the airport to see and propose to Amy in New Jersey.
