Google has failed on regular words. I usually only get empty search pages when I"m looking at obscure part numbers and such, but this time google returned nothing for "numbers associated with breasts" (I needed a numeric pun to play off someone else's mention of melons on facebook - and no, I didn't use quotes).
I suspect it might return something if I turn off safesearch, but I'm not gonna do that for this minor of a question.
Still, even with safesearch on that doesn't seem like a reason to return nothing...
Anyway, I went with the tried and true "8008" since I couldn't find something better.
Oh well.
RIP google.
