The wandering apostrophe; a so-intrusive creature
Once it was occasional; now it makes a feature
Of infesting poets' poems
And infiltrating stories;
It has no right to raise its head
It's only chasing glory.

The wandering apostrophe creeps into many plurals;
It sneaks around in manuscripts from Melbourne to the Urals
It seems to think it has a place
Prior to every S
It muscles into everything; a pushy thing, I guess.

Legitimate apostrophes? Two reasons to exist
One is denoting ownership,
The other - letters missed
It has no place in His or Hers, should never enter Its;
Unless it's standing for It(i)s
And then of course, it fits.
Onions doesn't need one (unless it's onion's skins)
One cat's bowl or two cats' bowls-
Learn this and you'll win
My poetic approval, but if you will or not-
The wandering apostrophe (I think)should soon be shot.
