Esperanto's translation being "it's all Volapük to me" is exactly the kind of linguistic shade I was hoping to find in that article.

Lobjan: It's Ithkuil to me.

Sadly the list does not include an entry for how you would express this sentiment in Ithkuil.

(both are of course conlangs)

But it's the same in Danish as well? Very odd for a real language.
