Read the tweets, these schools can’t even teach these moron’s proper English.
The irony.
Since you brought up the topic of grammar... The plural form of moron is morons . It is only necessary to add the letter s to the noun to make it plural (or to add es in the case of a noun which already ends with an s). When you instead add an apostrophe to a noun, as you did with moron's, you make that noun possessive.
There are also cases in narrative writing in which an apostrophe is properly used to indicate a "dropped" g in a spoken word that ends with the letters ing. Just sayin'...
Misuse of apostrophes has become so common that many Americans under the age of 50 don't even notice it anymore. But old farts like me still do! Please accept the friendly reminder in the spirit in which it was given, and then let's go to the store and buy some more ammo!
