Welsh is a ridiculous language that I am yet to be convinced is real.

EDIT: HAH, I KNEW IT
WELSH [i]MIGHT[/i] 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.
