Goof: When Dr. Weir distracts Dr. Lee with the game World of Warcraft there are several errors in the conversation. Dr. Lee explains he is level 75, WoW characters have a max level of 60. Even after the expansion pack was released, the one Dr. Lee says he has, the character can only go up to level 70. Martin Gero has since said that this was because at the time this episode was shot the rumor was that level 75 would have been the max for the expansion pack. He then used the term "jeweling". The correct term would be "jewelcrafting". In response to a the question "What is your race?", Dr. Weir responds "Mage." This isn't actually a race but a character class, which Dr. Lee should have picked up on.
