I swear, Fink just follows me around looking for typos. Everytime I make a typo there is Fink, right behind me, quoting my typos to ensure they are forever preserved.
EDIT:
As for Xhonzi's post... actually, irregardless of the joking in my previous post, I still have to agree with TheBoost. The term McGuffin was coined to describe something very specific, and things like the Death Star or the Ark of the Covenant, being HUGE plot points, are not it. Even if you want to say, "Star Was is NOT about the Death Star plans" or Raiders is more about the people trying to raid the ark than the actual artifact" those things are still the focal point of the entire story.
