It took me a bit of trial and error to find some podcasts that were worth listening to, but the How Stuff Works iTunes channel came to my rescue. Their first, and still best, podcast is Stuff You Should Know.
This week I listened to an episode about "Fainting Goats." Evidentially, they don't actually faint. It's an abnormal fight or flight reaction. And, super cute factor, it can happen to kittens.
