Finally, a superhero we can all believe in...Grammar Man! I hope he keeps a bag of apostrophes handy for all the poor shop signage up and down the country. And restaurant menus - they're often the worst offenders.
If I have one criticism it's that he's made more of a mess than the original graffiti. Perhaps in future he could do his corrections in chalk, or now that he's established and in the public conscience, maybe he could sign off with a simple exclamation mark! We'll know it's you, Grammar Man.
Keep fighting the good fight,
innit isn't it !
