In old-fashioned desks, one has a collection of little nooks or recesses
where a rolled-up paper might reside, called pigeonholes. As I learned it,
the pigeonhole principle was so named because the intuition was if you had
n+1 papers, there was no way to put them into n pigeonholes without
doubling up papers. The pigeonholes in the desk were called that for their
resemblance to nesting holes in a pigeon loft.
I think, though, that this only pushes the arbitrariness of the pigeons up
