My wierd friend Les in the Bay Area advises me that a unique horological event has come and gone. It was a special moment in Unix Time that occured on Friday, 13 February, 2009. The origin on the Unix time line is planted just after midnight, 1 January, 1970 and accumulates in units of seconds. Notably, on 2/13/09 at 23:31:30 (UTC), the Unix clock registered “1234567890”.
This event was unique enough in some circles to lead Unix Time enthusiasts to celebrate with parties and revelry in many parts of the world. I’m sure they partied like brain damaged test monkeys.
Naturally, Th’ Gaussling was not invited or even advised of this special event. [Update: This claim is incorrect. Th’ Gaussling was in fact advised of this auspicious occasion in advance by a nerdly friend, but failed to appreciate the gravity of it.]
Of greater interest might be the very next second. Apparently 1234567890 + 1 is prime (I have not personally verified this and probably will not get around to it before the next interesting Unix moment arrives- 9876543210).

Your friend is a serious, dyed in the wool, unrepentant, NERRRRD!
Consider yourself honored for not having been invited.
But from a purely clinical perspective I can say most reasons to party are half baked and tenuous at best. Nerds are by definition outsiders, and thus create reasons to party which exclude the greater society from which they’ve been banished.
