Kelvin Davis isn't the first Kiwi politician to take a crack at the opposition, and won't be the last.
At the weekend, the newly crowned Labour deputy leader, on live TV, lashed out at no fewer than seven high-ranking MPs before he was brought to heel.
- Kelvin Davis lets rip into senior Nats
- Jacinda Ardern lacks substance compared to Bill English - Paula Bennett
Some of his cracks were clever - "Paula Bennett [has] mastered the Lynn of Tawa effect" - some of it cruel - "Jonathan Coleman, the doctor of death".
And his attack on Gerry Brownlee was quite simply surreal - "We've got Gerry Brownlee, who's got the energy of a small hill."
But if the Te Tai Tokerau MP wants to make a career of slinging mud, he's come to the right place.
Here's some of the greatest insults Parliament has heard, and some of the worst.
