working...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.
