Ran across a first, just last week; an aggressive possum!
While closing the front blinds, I spotted a very large possum waddling across the street toward the house. It was dark, I was barefooted and didn't have my glasses on, but, I wanted to discourage it before it got into the philodendron bed so I ran out and confronted the (very fat) possum. Instead of running or playing possum, that sucker bared her teeth, hissed at me and kept coming, even when I kicked toward it and made loud noises! 
I suspected it was a very pregnant female en route to drop her excess baggage in the flower bed, so retreated to retrieve the garden hose (which the yard man had conveniently wadded up and dumped in the philodendon's)! Hoping she would not continue on while I struggled to untangle the (black) hose in the dark (without my glasses), I finally had to turn the water on in order to locate the end of the hose!
Once found, I managed to pull enough hose out of that infernal bird's nest to reach the possum, which was still hissing through bared teeth, and convince her she was unwelcome.
The moral of this story is, when going hunting, be sure you do not forget your ammo, and, watch out for those killer possums; you never know!
