I was wondering about the excessive precision in that date, but it looks like the author really did his homework: “A 2013 study published in Science estimated the age of the impact as 66,043,000 ± 11,000 years ago“. The number he used is well within even those unusually narrow error bounds.
In the Rubes, I’m sure the joke is that only a child would put a tooth under a pillow. When I first saw it, though, I wondered why she was saying the pillow was juvenile.
And thanks, zbicyclist, for calling the tip jar to my attention.

Is the Rubes saying something about the Tooth Fairy?
Synchronicity on the first – I’m in the process of reading a book on this very subject.
The tip jar on that last one is a nice touch.
@Scott, is the figure of 66M y.a. pretty close to accurate?
@Z Thanks for the “tip”. Made me notice the running figure, as in “Get the Hell out of here”.
That’s about right: https://en.wikipedia.org/wiki/Chicxulub_crater
