Acorns

If you’ve an oak tree in your yard,
You might get clonked a bit too hard
By acorns which come raining down
As cooler weather comes to town.

The acorn, with its jaunty cap,
Won’t nail you with a gentle tap
But one that’s apt to leave you bruised
So Mother Nature stays amused.

Beware then of the sneak attack.
A gust of wind may cause a whack;
And only then you might dispute
That harm can’t come from something cute.
