I happen to know that I have at least 2 grammar-experts who read this blog. So here's the question: Is it proper to say "On your mark, get set, go!" OR "On your markS, get set, go!"
Usually I can use logic to figure out what's right, but this makes sense both ways to me. YOU only have one "mark" to get on - so the first makes sense. But, then again, you're talking to multiple people here and they EACH have a mark. Which means there are multiple markS to be had.
I know, random. But a Google search would be fruitless since you never know if the person writing it is a good grammar-a-tition or not (how's that for a made up word!).
Naomi says "On your marks, get set, go". And I was about to correct her when I got stuck in this mental conundrum. Help me out.
