I don't remember the source but a few weeks ago I emailed this to myself. The link is to somewhere in Politico.com. The question is not about politics, or even erstwhile front-runner-of-the-week Newt Gingrich. Instead it's about terminology.
Lede of the day: "Oh, Newtie, excite us, delight us, make our knees grow weak."
Weak in the knees? I've heard the phrase for years, and read or heard the phrase in works going back till at least the beginning of the 20th Century. But where did this come from?
Do people really get weak in the knees from enthusiasm or excitement? Political, or erotic, or otherwise?
"Weak knees" has been used to imply fear for millinea. That makes sense.
But weak in the knees from excitement, delight, or arousal?
I usually feel anything but weak then. But maybe that's just me.
What's your take?
