I must suggest you visit this blog, which is basically photos of signs that have really random quotation marks on them. I am pretty sure my journalism friends will appreciate it.
Also on that note, B and repeatedly noticed one of those sign-holder people holding a sign that said "Condo's for sale," and I would always say, "Look honey, there's a condo for sale. Just one. Same condo's been for sale for a while, I'd say!"
Then the other day he called to tell me someone had wised up and removed the apostrophe from "condo's"!
