Tell the boys this story: (I swear it's true.)
For a short while, in pursuit of ever more MPG, the Prius looked like this:
(Yes, that's a plastic-wrapped drag-reducing "boat tail", mounted on a trailer hitch, tail lights integrated in the back. Same overall length as a Ford F-150, FYI.)
One day I was meeting friends at a pub, and there was a parking spot on the street, right in front.
A couple of minutes after I sat down, a very pleasant young lady walked up to our table and asked, "does anyone here own the Prius parked out front?"
I claimed it. ("Admitted" it? While thinking, "crap! Someone hit the car!?")
Then she asked, "WHAT is on the back of it??"
And I swear, from there we had an engaging conversation about aerodynamics. She was genuinely amazed.
We named our children Wunibald (Kamm) and Daniel (Bernoulli).
All 100% true! Except the last line. Who would name a kid Wunibald?
