If you know how to translate "Can I Haz Cheezburger?" in Catalan, then you might register LOL.CAT (I can't figure out if it's available or not, the registry says yes, Gandi says no). The .cat domain is open for all to register but one has to publish a website in Catalan within six months of registering a domain name, and it's twice as expensive on average. Plus you'd better not approach the punt CAT registry with a browser that doesn't speak Catalan, or you'll be greeted by this:
I wish them good luck.
