Perspiration

The story:

At the beginning of the song Madonna starts by saying, "for inspiration", but I always thought she was saying "perspiration". I thought this was a little weird, but Madonna is odd, and anyway the song is about dancing, so I figured she is working up a sweat. My sister heard me singing it in the car one day and just burst out laughing. Then she told me what the lyric really was...too bad, "perspriation" is better.
