The Robotic Manipulation - S4-E1
Corrected entry: In a conversation with Penny, Sheldon says "Progidy" instead of "prodigy". Definitely not a mistake he'd make. (00:19:50)
The Robotic Manipulation - S4-E1
Corrected entry: 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. (00:11:19)
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 Robotic Manipulation - S4-E1
Corrected entry: Howard explains the ease with which he "borrowed" the programmable robot arm thus : "You just have to take it out to your car as if you own it". Howard doesn't have a car - he has a Vespa scooter, and there is no way he could carry the robot arm on that. (While we are on the subject, how does he transport it from Sheldon and Leonard's apartment to his house?).
Correction: His mother very likely has a car (we've heard her say that she's driving back to the grocery store), which Howard very likely used for this occasion.
Deus ex Machina explanations for errors do not invalidate them. Howard does not have a car and at no time does he mention borrowing one from anyone.
Correction: Sheldon actually says "I suppose she will have to have access to our progeny".
