Key instead returned to his Beehive office with cries of "shame" and "apologise" following in his wake. Labour MP Annette King felt peeved enough to label him a "scumbag".
The Prime Minister's office later said he had been referring to Labour's criticism of the number of diplomatic protection squad police employed in ensuring his safety, compared with his predecessor, Helen Clark. That criticism has extended to questioning why an officer sits in the gallery while Key is in the House.
It is the Commissioner of Police and his senior staff who determine the level of protection - not Key.
However, the Prime Minister obviously felt vindicated - that the unfortunate incident had provided the justification for the level of security around him. But Labour's campaign has obviously struck a raw nerve.
Yesterday was the penultimate day of Parliament before it rises for the election. It was some finale.
Labour's Trevor Mallard later accused National's Tau Henare of making a Mongrel Mob salute. Henare said he had been making the Hawaiian "hang loose" salute.
And there was a plea from Assistant Speaker Ross Robertson to MPs not to treat the debating chamber like a public house and instead show respect for one another. "Courtesy is contagious," he said. Sometimes, maybe - but not yesterday.
