We have massive oaks in our front yard. Where there are oaks, there are acorns (and this year was a bumper crop). Where there are acorns, there are squirrels. Sometimes, there are more than a dozen just outside the door.
I'll admit, I enjoy throwing open my front door and yelling "HAH!!!!" at them and watching them scatter like mad. It's an explosion of squirrels. Besides, the little boogers are so fat from the acorns it's a wonder they can do more than waddle. They need the exercise. I'm doing my Christian duty by providing it for them.
