It was the second day of the Great Dye War. It was the pursuit of the hirsute as Winston Peters continued his campaign to get to the roots of what - if true - would be a real prime ministerial cover-up: that John Key dyes his hair.
Those MPs falling into the category of the follicly challenged - bald or rapidly trending that way - could only sit back in envy that both Key and Peters still have enough thatch up top to dye for.
Not that anyone would accuse Peters of such a practice. These days, his hair is streaked with large tufts of white. It is the look of wisdom that comes with age.
Key would not concur. The Prime Minister has a sense of humour. But he could not let the suggestion that he was hostage to vanity go unchallenged.
He struck back at the first opportunity when Peters probed him on the blow-out in the construction costs of the SkyCity convention centre project.
