For the International audience, the episode title "too many cooks" derives from the phrase "too many cooks spoil the broth". This describes the situation where having too many cooks does improve the end-result, but actually becomes counterproductive and either slows down the work or ruins it all together. In this case, the phrase is used figuratively with respect to the Special Agents. The phrase was initially used in 1575 by historian John Hooker. A later version is "too many cooks in the kitchen", both versions have the same meaning.
