While Sheldon and Leonard are conversing in the cafeteria, Sheldon says Ramona "has a very unique way of revering me." When something is unique, it has characteristics different in every way from everything else. Therefore, the "very" is unnecessary; like saying "very perfect." Sheldon would know this and would comment on another person's use of it, let alone he would not say it himself.
As Nowitzki is unpacking the Thai food she removes two white cardboard and one black plastic cartons from the bag. In the next shot the two white cartons have vanished. She then removes a second black plastic carton from the bag, and in the next shot the two white cardboard cartons have reappeared as she removes a third black plastic carton from the bag.
At 04:12 into the show Howard, Raj, Leonard, Sheldon and Ms. Nowitzki are sitting at the table in the cafeteria. Howard has his hands and arms resting on the table next to his lunch tray. At 04:13 the angle reverses and we see Howard from the front sitting at the table with his hands and arms at his side and not resting on the table next to his lunch tray.
At 09:46 Leonard and Sheldon are seen sitting in the cafeteria with Ms. Nowitzki having just brought Sheldon his breakfast. Sheldon can be seen picking up his silverware from the left corner of his tray. After two quick scene changes Sheldon is seen at 09:55 again picking up his silverware from the left corner of his tray. Immediately following this error another series of errors occur involving the knife and fork Sheldon is holding magically changing hands from one scene to the next. At 10:04 we see Sheldon holding the knife in his right hand and the fork in his left. At 10:10 we see him switch hands so the the fork is in his right and the knife is in his left. At 10:11 the angle reverses and we are looking over Sheldon's shoulder and the fork is seen in his left hand. At 10:13 the angle changes again and we can see the fork in Sheldon's right hand and the knife is now sitting on the top right corner of the his tray.
When Sheldon tries to communicate with Leonard using Morse code, he explains that he chose that way because Morse is encrypted. Actually, Morse code is encoded (it is a code) but by no means encrypted (a message can be understood by an observer if intercepted).
