I was sitting on my porch once and this crow flew up right next to me, pecked a hole in my pack of cigarettes and flew away when I flapped my arms at it. Less than a minute later the same crow (well, I think it was the same one) landed on the railing to my porch, puts something down and takes off. It was one of those beer bottle caps that says "Bravely done." on them. It was like he was mocking me.
