You have seen it. An apostrophe where it shouldn't be...or missing in action, when desperately needed.
Have you been tempted to whip out a Sharpie, and become a one-man/woman grammar Nazi?
Well, meet Bristol, England's self-appointed grammar cop. He has even manufactured his own, "apostrophiser," with which to fix those nagging grammar issues.
I love him.
With every fiber of my being.
