I heard something from INSIDE the ammo can. Yikes. I've heard about hamsters in geocaches...could it be? When I opened the can, quacking ensued, feathers flew, and there was a general sputtering and commotion. When I listened carefully, I could tell through the Donald-Duck accent that I was being insulted! I definitely heard "Avast ye bilge-sucking . . ."— well, you get the idea! Fortunately, I had just studied the remarkably useful information at http://uncyclopedia.wikia.com/wiki/Duck_(language) and so I was able to QUACK! communicate QUACK! to the little QUACK! pirate and QUACK! assured him QUACK! that I meant QUACK! no harm. This resulted in the smoothing of ruffled feathers and withholding of further talk about cutlasses, scurvy dogs, and hempen halters. Very quickly I will be finding a new home for this little buccaneer. I have a special crow's nest in mind...
