“Oh dear, oh dear, OMG, oh dear, oh dear, need to go rest in a darkened room,” David Cameron read from his file of papers at the Commons Despatch Box.
The PM’s critics might well wish he would do just that.
But this wasn’t Mr Cameron’s gruelling charm offensive around Europe catching up with him.
No, he was quoting Labour MP Madeleine Moon’s desperate tweet posted after Monday night’s meeting of the parliamentary Labour party.
And – not the best at hiding it when he has some mickey-taking ammunition up his sleeve – the Tory leader was positively gleeful.
“I expect she (Ms Moon) will find the rest of her party will be there with her,” he continued triumphantly.
The desperate tweet had emerged after shadow defence secretary Emily Thornberry clashed with MPs over Trident renewal.
Urging them to keep an open mind on the replacement of the UK’s nuclear deterrent, she suggested the system would be as out of date as having Spitfires patrolling the skies within a few decades.
Taking up the charge from the MPs who tried to shout her down at the meeting, Mr Cameron praised her “talent” in being able to “insult” both Spitfire pilots and the submariners at the same time.
Perhaps the PM took his lead from his opposite number who was uncharacteristically light-hearted at the start of the weekly onslaught.
In keeping with his now routine PMQs approach, Jeremy Corbyn asked a question from a member of the public.
This time it was the turn of Rosie, who is “in her 20s”.
Cue laughs and pointing at Labour’s chief whip Dame Rosie Winterton, perched on the end of the opposition front bench.
She smiled through gritted teeth as one MP – forgetting panto season is over – kindly cried: “Oh no, you’re not!”
Instead of moving swiftly on, Mr Corbyn – sporting his ‘I love unions badge’ – turned to her as he attempted to segue neatly into the substance of his question – housing.
“The Rosie who has written to me doesn’t have the same good housing that the chief whip of our party does,” he remarked.
It was irresistible for Mr Cameron.
“When you get a letter from the chief whip, that normally spells trouble,” he quipped.
Maybe the ugly sister so intent on revealing Dame Rosie – an MP since 1997 and former minister – is not “in her 20s” should expect to find one on his doormat any day now?
