Sheldon refers to the object with which he threatens Wolowitz as a Chinese throwing star, when in fact it is a Japanese throwing star known as a Shuriken (shu = hand, ri = release, ken = blade).
When Sheldon says, "It smells funny in here," while wearing the Iron Man helmet, the studio lights are clearly reflected in the mask.
Sheldon is known for being an overly hygienic mysophobe and very strict about who can touch his food, but in the cafeteria, while discussing mummies and zombies, Leonard gives Sheldon a cookie, and he eats it.
He trusts Leonard because Leonard prepares his food at home.

When the parking spot is shown, a handicapped logo can be seen in the next spot. This would suggest it's not assigned and for public use. Due to the limited number of people allowed to use them, these spots see less use than average spots (and in this case assigned spots). Yet when listing the advantages of this spot, Sheldon doesn't mention this, even though he *does* list the similar advantage that as a corner spot it reduces the chance of door dings by 50%. The handicapped spot would lower the chance of dings even further.
