Have you ever heard of this way of getting wax out of your ears?

I saw some famous doctor giving a lecture on public television today, and he said it was really bad to shove Q tips into your ear canal, that you should get wax out of your ears this way instead: you pour a drop of mineral oil into your ear, and then lie down for about an hour on your side with that ear up. After that, the wax should just come right out.

Have you ever of that? Ever tried it? How’d it go?
