Blushing

Why did I not realize that the witticism "A hard man is good to find" is sexual in nature until about an hour after I quoted it to a class?  I had envisioned a "hard man" being a tough, rugged fellow that drinks a lot.  And why did the students not just start laughing at me?  And why did I attribute this quote to Oscar Wilde, when apparently it was said by Mae West?

As my wife said, I've had quite a day.

Oscar Wilde's "The Importance of Being Earnest"

Oddly, the only work of literature I can compare this play to is Don Quixote: I read every line expecting to be amused, and was rarely disappointed. It is pretty much every impression I ever had of Wilde, in play form.
