And I'm on tonight
You know my hips don't lie
And I'm starting to feel it's right
All the attraction, the tension
Don't you see baby, this is perfection
-- Shakira, "Hips Don't Lie"
I was listening to this Shakira song, and I started thinking about the lyrics. Your hips don't lie? But wait a minute, whose hips do lie? How do they lie? About what? I don't understand.
