The Long Distance Dissonance - S10-E24
Continuity mistake: After the 'Ramona' conversation between Sheldon and Penny ends, Sheldon leaves Penny alone on the couch. Penny looks up to the "Amy and Penny" painting and says "Don't look at me like that, I tried." In S10 E10, Amy gave the painting back to Penny, which was hung in Leonard's living room.
The Long Distance Dissonance - S10-E24
Continuity mistake: When Sheldon takes a plane to see Amy in Princeton, the plane he is on has 2 engines when it takes off and 4 engines when it lands. It's a direct flight from LAX so he wouldn't have changed planes.
The Recollection Dissipation - S10-E20
Continuity mistake: When Howard and Bernadette are talking in the kitchen by themselves, Howard's bottle of water keeps moving between shots.
The Escape Hatch Identification - S10-E18
Continuity mistake: Stewart eats a ham sandwich when he and Raj are talking alone in Howard's and Bernadette's living room. On at least one occasion the sandwich's size gets larger, not smaller between bites as Stewart is eating it.
The Fetal Kick Catalyst - S10-E6
Continuity mistake: Near the end of the episode where Sheldon and Stuart are drunk and talking about how Sheldon never leaves the house without a paperclip, the amount of Mimosa in their glasses suddenly decreases between shots.
The Brain Bowl Incubation - S10-E8
Continuity mistake: When Raj puts down the rubber gloves when talking with Isabella, the gloves completely vanish 6 shots later with nobody touching them.
The Dependence Transcendence - S10-E3
Continuity mistake: Bernadette is talking to Raj's dad on the video phone. In the close up, her fingers are wrapped round the phone but in the long shot, she is holding her fingers behind it and balancing it with her thumb.
Suggested correction: Not being able to afford doesn't necessarily mean he doesn't have the money, especially a man like Sheldon. He works with a budget and he sticks to it. In his budget he has a certain amount set aside for rent, anything more than that and he can't afford it alone.
Nonsense. If he was sticking to a "rigid budget" he wouldn't have even thought of lending a hopeless credit risk like Penny a single cent. Instead he throws a huge bankroll at her without even discussing a repayment plan.
Rubbish, I stick to a strict budget but still have the money to lend to close friends. Like Penny is to him.
He might have different budgets for different things. People could get a higher margin because they could be of more use to the scientific mind of Sheldon.
