The Military Miniaturization - S10-E2
Corrected entry: When Raj and Howard are trying to decide whether to accept Col. Williams' offer, they can't think of any lawyers to ask for help with potential legal issues; they both seem to be forgetting that they do know a lawyer: Raj's sister Priya.

The Wheaton Recurrence - S3-E19
Corrected entry: In previous episodes, it's mentioned that Leonard is lactose intolerant, but at the bowling alley he eats from a plate of chili cheese fries.
Correction: Just because he's lactose intolerant doesn't mean he can't have dairy (as opposed to Howard's peanut allergy where he can't have any peanut product). In fact, in several episodes others have made fun of Leonard's flatulent as a result of him having dairy, evidence that he's had dairy products before.
Correction: Given how things ended with Priya and Leonard, it probably would have been very awkward for both of them. In addition, she knows far more about Indian law than American law.

It is noted (by Leonard) in a previous episode that Priya is qualified to practice law "in three countries, and your face!" Presumably, as she is there for some time, works for a law firm, etc, one of those three countries is the US.
