As kisses go, it was more peck than pash.
The last of the 19 carbon tax bills - carefully branded as the Clean Energy Future legislation, mind - had passed through the lower house, and the Labor members were popping their corks.
They applauded, Prime Minister Julia Gillard beamed with delight, and Climate Change Minister Greg Combet's oft-funereal features lit up with something akin to joy.
Everybody on the government side ran about shaking hands and embracing, and for a moment it was like we had swapped the House of Representatives for the set of Oprah.
Then, snaking up the outside of the knot of well-wishers surrounding Gillard, came a silver-haired comrade with whom she is not accustomed to having cuddles.
Foreign Minister Kevin Rudd gave a smooch and a little hug of congratulations, and if it was more awkward than it was sweet, well, nobody much noticed. Except the news photographers, the Opposition members and the entire press corps, gathered to watch the historic vote.
The Coalition front bench whooped and hollered like teenagers surveying a particularly saucy game of spin-the-bottle.
The serious business of legislating stuff was done, and the way was gloriously clear for the usual posturing and stunt work of question time.
But for once, the politicians were outdone on this front by members of the public gallery, who rose en masse during a question from Liberal MP Karen Andrews to show their opprobrium of the government and its carbon tax.
''NO MAN DATE!'' the protesters chanted, stringing out the syllables in a way that had the odd effect of making them sound like non-English speakers demanding that no man be allowed to take his lady friend to the pictures of a Saturday night.
''Demo-cra-cy is DEAD!'' they continued, apparently oblivious to the fact that in nations less democratic than ours, they would risk a robust Tasering for such larks.
As it was they were swiftly bundled off by the parliamentary guards.
''It is a privilege to be in the gallery,'' Speaker Harry Jenkins warned.
Gillard rose to continue speaking, only to be interrupted twice more by protesters in the two remaining public galleries, chanting the same slogans.
This disruption almost got in the way of the Opposition leader Tony Abbott's own disruption, which happened in its usual just-pre-3pm timeslot, the appointed hour at which Abbott generally rises to move that standing orders be suspended so he can censure the Prime Minister.
As Leader of the House, Anthony Albanese spoke against the motion, former Opposition leader Malcolm Turnbull and former prime minister Rudd, whose political fates were so inextricably linked to former attempts at legislating for a carbon price, sat exactly opposite each other.
They mirrored each other's body language: arms folded, chins high. Silent.
