It's like my grandmother used to say about my dad: "He's not hard of hearing. He's hard of listening." Me, I'm not hard of reading, I'm hard of thinking.
No seriously, don't know if I've come across it before, but sometimes if you aren't primed to *think* about something, a quick skim does no good. So maybe I read it, but just didn't think it. Can't say.
Either way, it's very clever.
