The Platonic Permutation - S9-E9

Continuity mistake: In episode 16 of season 1, Penny is talking about making a cake for Leonard's birthday and states she knows his birthday because she was checking a horoscope for him. But in this episode she does not know when his birthday is, which leads to Leonard revealing he was secretly reading Penny's diary. (00:40:00)

Suggested correction: It's certainly possible to forget something you knew eight years ago.

This is perhaps true for two people who rarely have contact, but I would list this as a character mistake. Penny and Leonard are in a serious relationship and are married at this point.

Bishop73

I forgot my wife's birthday on a number of occasions. It's one of the reasons she is now my ex-wife.

There's a difference between forgetting and not knowing.

Bishop73

This is also a couple who BOTH forgot it was their anniversary.

The Matrimonial Momentum - S9-E1

Continuity mistake: In the first half of the episode while in Las Vegas, Penny's hair is short; however, later in the episode when she is back in the apartment speaking with Sheldon, her hair is much longer, albeit tied back in a bun, but very obviously much longer and a very different color. The scene from Las Vegas to her apartment was less than 24 hours apart and would have been impossible for her hair to have grown so much.

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.
