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.
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).
