I was strolling down the street when I caught a glimpse of a squirrel on the far side of a tree trunk. It had a cigarette in it's mouth.
Now I now what you're thinking, it just picked up a cigarette but and was carrying it in it's mouth. This is indeed likely, but I find it unusually for squirrels to put objects in their mouths if they are not nuts. I never saw the squirrel again, so you can draw your own conclusions, but I know what I saw.
