From wikipedia: In fiction, a MacGuffin (sometimes McGuffin or maguffin) is a plot device in the form of some goal, desired object, or other motivator that the protagonist pursues, often with little or no narrative explanation. The specific nature of a MacGuffin is typically unimportant to the overall plot.
The scene when Robin opens the MacGuffin container is a reference to a similar scene in Pulp Fiction. The briefcase with unrelieved contents from the movie is one of the most famous examples of a MacGuffin.
The "Egg MacGuffin" is a reference to the Egg McMuffin from McDonald's.
This episode's title is a reference to Skunk Fu!, whose episode names start with "The Art of..."
