Never give a Welshman bad directions...

Traveller's Curse After Misdirection
(from the Welsh)

May they stumble,
stage by stage
Of an endless pilgrimage,
Dawn and dusk,
mile after mile,
At each and every step, a stile;
At each and every step withal
May they catch their feet and fall;
At each and every fall they take
May a bone within them break:
And may the bone that breaks within
Not be, for variation's sake,
Now rib,
now thigh,
now arm,
now shin,
But always, without fail, THE NECK.
-- Robert Graves
