Welsh is a ridiculous language that I am yet to be convinced is real.
EDIT: HAH, I KNEW IT
WELSH MIGHT BE REAL BUT THIS NAME ISN'T
It's two villages, Llanfairpwll and Llantisilogogogoch (both of which are admittedly ridiculous on their own), that some guy had combined, their names merged, when a railway station was going to be put in Llainfairpwll. They did it just so they'd have a really long name and get put in the record books, attracting tourists.
