I used to think Toto's Africa contained the line "I spent my life trying to get away from you," (rather than "it'd take a lot to take me away from you.") What makes it more entertaining is that the follow-up line is "it's something that a hundred men or more could never do," thus leaving me with the image of a woman with a hundred or so people just stuck to her like a magnet.
