It's all Greek to me!

A question on this evening's Only Connect required contestants to recognise statements in a variety of languages which were the idiom equivalent to the English It's all Greek to me. Curiously, neither team could crack it. Or perhaps not so curiously: it's not uncommon for me to be able to answer only one question in the entire programme, but for it to be a question that foxes the contestants (who have no trouble with other questions which I find impenetrable).

Anyway, in addition to examples I recognised (French: Pour moi, c'est du chinois) was one I hadn't met before: Ĝi estas laŭ mi Volapukaĵo!, which is Esperanto for It's all Volapuk to me!

I am delighted by this, and relieved to have it confirmed by Omniglot alongside a fine collection of others.
