David Seymour tried to take a dig at the Green Party on Wednesday, but ended up digging a hole for himself instead.
The ACT leader tweeted a photo of himself taking the bus to Parliament just after 9:30am, along with a snarky comment aimed at the environmentally-focused party.

"Took the bus to work today but didn't see any @NZGreens MPs on board!" he wrote.
Mr Seymour might have been pleased with his provocative comment, but others on Twitter were less impressed - and many had their own rebuttals.
The Twitter thread quickly descended into the roast of David Seymour, with hundreds taking shots at the politician.
Some suggested - including Labour MP Deborah Russell - that there were no Green MPs on the train because they were all at Parliament on time that morning.
Others poked fun at Mr Seymour for seeming to think there was only one bus available in Wellington.
Mr Seymour's recent elimination from Dancing with the Stars NZ was also a topic of discussion.
But it was the simplest of insults that proved most devastating.
It's not the first time Mr Seymour has sparred with the Green Party. In February he called Golriz Ghahraman a hypocrite when she accused him of "overly sexualising" women after wearing one of the University of Auckland Meat Club's t-shirts.
