"Used Battery's Only"

This is clearly an apostrophe disaster of epic proportions. In a mere 12 words, the person who wrote this sign managed to use an apostrophe twice where no apostrophe belongs! What is truly special to me is that the apostrophe is not only used incorrectly twice, but it is used incorrectly in two different ways. As you can see, the first apostrophe is used instead of adding an "ies" to properly pluralize the noun battery. The second apostrophe is added to the verb creating some sort of mutant contraction.

Upon seeing this sign, my first impulse was run through the store, find a red Sharpie, and add some edits. Then, on second thought, I decided to take a picture and blog about it instead.
