Ears are strange...

humanear_anatomy
...not only does the skin inside the ear canal grow constantly out from the inside in a spiral (a bit like a crazy conveyor belt) to keep the canal free of ear wax and other debris, but as you move your eyes to focus on things, the ear drum flexes in the same direction (a bit like a cat/dog ear but not quite as good) to point more specifically at things that could be making interesting sounds.

Try it, you can (kind-of) feel it happening.
