The Zarnecki Incursion - S4-E19

Character mistake: As they drive to Todd Zarnecki's to confront him, Sheldon says, "I almost feel sorry for the poor fool, sitting in his split-level suburban ranch..." Architecturally, split-level (technically three levels joined by half flights of stairs) and ranch (single level) are separate and distinct designs. There is no "fusion" of the two. I can't help but think Sheldon would have corrected anyone who said the same thing.

The Prestidigitation Approximation - S4-E18

Continuity mistake: Near the end of the episode, in the canteen scene, Howard shows the card trick to Sheldon again. The card at the bottom of the deck is the 2 of hearts as he takes them from the box. Sheldon then takes this card from near the top of the deck when Howard puts them on the table. The deck is not shuffled between times.

The Robotic Manipulation - S4-E1

Character mistake: While driving towards the restaurant, Amy mentions she uses dandruff shampoo for her "dry" scalp. Dandruff and dry scalp have the same main symptoms, which are falling flakes and an itchy scalp, but they are two different conditions. In dry scalp, the skin gets irritated and flakes off. With dandruff, the cause is too much oil on the scalp. That excess oil causes skin cells to build up and then shed. Therefore dandruff shampoo should be used for an oily scalp, not a dry scalp.

Upvote valid corrections to help move entries into the corrections section.

Suggested correction: Except there are dandruff shampoos that specifically treat dry scalp. In addition, dry scalp is commonly caused by dandruff.

More of a continuity error regarding this is that much later she claims that lice isn't attracted to her hair cos of her naturally oily scalp (contradictory).

Then that should be entered as a mistake. What was entered isn't a mistake.

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.

Show generally

Question: How come Raj has no problem speaking to his mother, but, when around other women, such as Penny, he immediately stops talking? Also, why does he have to whisper in someone's ear if he wants to ask Penny something?

Answer: Because Raj's selective mutism seems to be caused by women that Raj sees (on some sort of conscious or subconscious level) as a potential sexual partner. An attribute that wouldn't apply to either his sister or mother.
