Another trick (that really only pays off if you're using a huge amount) is to put them in a pot with a lid and shake the shit out of it. The husks get ripped right off!

I never actually do it because A) it takes a lot of shaking and B) you have to clean the pot, but I could see it being worthwhile if you were making a bunch of chili or soup or something.
