Take a look at the bravery of the duckling facing a crocodile.
Now, I don't usually consider ducks to be overly smart creatures, and even less so after this. That being said, you can't argue with results. This little fellow had a crocodile on his tail, but instead of running, decides instead that it's a better idea to peck the advancing wall of teeth first, presumably in hopes of chipping them or something, and then proceed to run as fast as his adorable little feet will carry him. I do have to say tho, for such a dim duck, he's a cute little bugger.
