MPs openly laughed at Brexiteer Mark Francois as he committed a magnificent self-own while complaining about Theresa May's Article 50 delay.
The self-styled Brexit war poet is one of a handful of hardcore Brexiteers who have steadfastly refused to approve the PM's Brexit deal in Commons votes.
Mr Francois is deputy chair of the European Research Group, a hard Brexit group of Tory backbenchers, many of whom have been campaigning for Britain to leave the EU - with or without a deal - for decades.
They've been sticking to their guns, insisting the Withdrawal Agreement is not, I dunno, 'Brexity' enough for them.
But as Mrs May returned from Brussels with another delay to Brexit, he rose to his feet and accused the Prime Minister of being "obstinate."

He said: "The Prime Minister's first extension was based on the fact that we would ratify the Withdrawal Agreement.
And in what was effectively 'MV3' [a third meaningful vote] we turned it down again.
"And now she's been given another extension longer than she asked for, yet again on the basis that we will somehow ratify the withdrawal agreement.
"Perseverance is a virtue, but sheer obstinacy is not."

MPs openly chuckled at the sheer brass neck of the outburst.
Mr Francois, realising the irony in his statement, smiled and winked theatrically.
Three times.
By this point, Tories on the benches in front of Mr Francois were literally turning round in their seats to mock him.

But Mr Francois battled on: "Prime Minister. If as I suspect, the leader of the opposition strings us along in these talks and then finds a pretext to collapse them, and then calls a confidence motion - what will you do then?"
Which may have been a fair question, but by this point it had been entirely undermined by his earlier, ballsier gambit.
Mrs May replied: "I will continue to argue for the Conservative Party remaining in Government. A party which has led to a situation in this country where we see record levels of employment, 32 million people with tax cuts, a modern industrial strategy, 1.9 million more people in good or outstanding schools.
"We're delivering for people and that's why this party should remain in government."
