Orange you glad Shakespeare didn't say banana?

I first read "Macbeth" when I was 12. Barely a year hasn't gone by that I haven't read it again. I've seen dozens of productions of it. And yet...

...only tonight did it dawn on me that the porter says, "Knock, knock. Who's there?"

Yet another thing Shakespeare invented that he doesn't get credit for. Or blame.
