Stop! Super-prime!

It is now sixty-seven days to the release of Rosemary and Rue. According to Wikipedia (source of a great deal of numerological wisdom that I don't actually have to type up from scratch), sixty-seven...

...is the nineteenth prime number. (The next up is seventy-one, the next down is sixty-one.)

...an irregular prime. (Don't ask.)

...a lucky prime. (Again, don't ask.)

...the sum of five consecutive primes (7 + 11 + 13 + 17 + 19).

...a discriminant to the Heegner number -67. (I don't even know what this means, but it's cool.)

...since 18! + 1 is divisible by 67 but 67 is not one more than a multiple of 18, 67 is a Pillai prime. (This, I do know, but it would take an hour to explain, and I'd need puppets or something.)

Also, apparently, "In a Voronoi diagram created using points from the prime spiral, no prime less than 10242 will have a rounder Voronoi cell than 67." Cool, huh? There is no Highway 67, making it the highest two-digit number not currently designating any highway in the Interstate Highway System of the United States. Oh, and in the Prisoner game I was in once, my ex-boyfriend was "67."

Pardon me. I'll just be over here with my ravens and my writing desks, going cheerfully mad.

When the writing desk starts doing this, you can consider yourself on the way.
HAHAHAHAHAHAHA!

I should install a voice box.

"He takes the glasses off to see/Yellow cat's eyes turn on me..."
If that happens, you'll never find my body.
Ooooooo - 6 1/4 years until I'm an irregular lucky prime. Go me!
Yay!
Your number-geekiness is very sexy. Just sayin.
Awwww, thank you.
Ooo, overclocked hamsterwheeling!
I go zoom!
Interstate 67 has been reserved for a possible new Interstate in Pennsylvania. (Because PA has insane politicians, that's why.)

There is a US Route 67 though. Runs from Texas to Iowa.
AWESOME!
. . . 67 is a Pillai prime. (This, I do know, but it would take an hour to explain, and I'd need puppets or something.)

I think this should be your next set, all by itself. :-)
That'd be sort of awesome. I should do that.
How about writing the explanation as a set of teaching songs, and the set then performs those with the hand puppets?

I love interesting number properties like that. Although there was the time I turned 49 and declared that there was "nothing special about that number except that it's prime". Er, OK, I'm a programmer, we don't do basic arithmetic...
Let me finish my epidemiology teaching songs first, and I just might!
You've added some new interesting properties to my list - I was aware of some of them as our house number is 67 and I'd decided that it was a lucky prime.
Awesome.
GOING cheerfully mad? Thought you were already there....

;-)
This is a new, limited-edition flavor.
Oooh, then I shall have to collect it :-D
