Thanks, pennyrat.
Proposed by me in an even earlier thread, I think Tiarnan, Bríd Mhór, and kokoshneta have now confirmed it, at least as a literal translation. If anyone can think of a proverb that fits, please don't hesitate to put it forward here.
Here's a sound file for a Conamara/Cois Fhairrge-style pronunciation:

/air´o: toNtə er´ is´k´ə k´u:n´/
Slender r in the middle or at the end of a word in Irish has a buzz somewhat like the French j in
je, which I have written as "rh" in the phonics.
You may also hear
tonnta pronounced TON-tee /toNti:/ or TOON-tuh /tu:Ntə/ in Connemara.
