It was two weeks ago and Labor tried to make political mileage about Turnbull's huge $200 million personal fortune and private investments in the Cayman Islands.
In what some political commentators are already pointing to as a watershed moment for the new Turnbull era, the PM actually used the awkward revelation to his benefit, hammering Labor.
"If the honourable member (Bill Shorten) wants to go round wearing a sandwich board saying, 'Malcolm Turnbull's got a lot of money', feel free," he said at the despatch box.
"I think people know that I've got a lot of money."
It was immediately seized on by some as a potential new slogan for the struggling opposition leader.
And just a reminder: Yes, Malcolm Turnbull is so absurdly wealthy he decided not to move into the prime ministerial residence because his Sydney waterfront mansion is much nicer.
Well The Australian's very funny cartoonist Jon Kudelka has called Turnbull on his bluff, making a whole clothing range emblazoned with the statement.
BuzzFeed staff bought some of the range to check if the site was a prank. As you can see here, nope, it's real!
