Quotable Lines in Die Hard

I find that I quote many lines from this movie because they fit sooooo well on many daily occasions. For example, when someone asks how I am doing (and it really isn't a great day), I tell them "all things being equal, I'd rather be in Philadelphia." Now, I am well aware that this is a line used by W.C. Fields; but, since I am a child of the 80's, I always give credit to John McClain.
