Theres an anonymous Grammar Vigilante in Bristol, UK. A gentleman who is going around under cover of darkness, mending apostrophes. And by mending, I mean wiping out the one’s that shouldnt be there and adding the one’s that should. Theres a radio show about him going out later today.
The Grammar Vigilante carrie’s an Apostrophiser (spoiler: its just a big stick) around with him to expunge the errant punctuation and to add in anything missing. To be honest, he actually sounds a bit creepy in real life (theres a quick interview with him on that link), but I think this is a great idea.
I might start a similar campaign here.
