His setting of a New Zealand, if not world record began during ministers' question-time with Heatley noting Labour's housing spokeswoman Annette King had credited a visit by him to a block of Housing New Zealand's flats in Auckland's Symonds St as resulting in the tenants getting new lino in the entrance.
While Heatley was "delighted" at the thought of the residents enjoying their new flooring thanks to his efforts, a check of his diaries had revealed he had never visited the block.
King then got to her feet to ask whether the tenants had been confronted by a Heatley imposter. Or was it a "linocut' of him? This atrocious pun provoked an extraordinary response from Heatley with him emitting a gargling-like "ahhh ... ahhh ... ahhh ... ahhh". It sounded like a cacophonous mixture of a strangulated Father Christmas shouting "ho ... ho ... ho" and a braying donkey.
Heatley may now be dubbed the Minister of Silly Noises .There will not be a repeat, however. Agreeing with Labour that Heatley's unique contribution to democracy was "unusual", Speaker Lockwood Smith ruled it out of order.
It was not the only "unusual" performance of the day. Swooped upon by reporters outside Labour's morning caucus meeting, party leader David Shearer confirmed he was going to give his MPs a "rev-up" following last week's lapses in discipline.
When it came to rev-ups, however, Shearer was more than pumped. He was testosterone with legs. The judges would have demanded a drug test. It would have been positive. But it would have been legal. Shearer was merely exhibiting the side-effects of one of the strongest drugs of all - power, or, in his case, the preservation of it.
