I see quotation marks on everything lately. I saw a guy wearing a name tag the other day. The store had actually put his name in quotation marks.
I said, "So, you're allegedly George?" and he cracked up, knowing what I meant.

There are a few other uses for quotation marks aside from literal quotes, but emphasizing random words (like "stop" in the title above) is not one of them.
