The PM said he would stay on until the Tories choose a replacement and that he has done, and rather than twiddle his thumbs and write some handover documents, he has used his notice period to behave in utterly bonkers ways.
From having a jolly while the rest of the cabinet held a Cobra meeting, to behaving in petty ways with his rivals, he's really amped up his "no f***s given" vibe in the last few weeks.
Paul Dacre, the former editor of the Daily Mail, and billionaire Tory donor Michael Hintze are also said to be in line to be ennobled in the next couple of months so it is looking like a cracking list indeed.
3. Had a jolly in Chequers
When the UK prepared for an extreme heatwave in which temperatures in parts of the country reached a record breaking 40.3C, Johnson hung out in his Chequers retreat in Buckinghamshire instead of chairing an emergency Cobra meeting about it.
Labour’s Angela Rayner said Johnson had “gone missing in action again”.
“He’s back to his old tricks of skipping important Cobra meetings.
“The public will have no confidence in this zombie Conservative government responding swiftly and decisively to this national emergency as this disgraced prime minister prepares to party while Britain boils.”
If that wasn't bad enough, Johnson spent some valuable time being filmed at the controls of a Royal Air Force combat jet. He gave a thumbs up as he took the reins of the jet flying through the sky before making a speech to business leaders at Farnborough air show.
"After three happy years in the cockpit, performing some pretty difficult if not astonishing feats, I am about to hand the controls over seamlessly to someone else," he joked.
People thought it was a waste of taxpayers money and who can blame them?
\u201cFirst footage of the PM at controls of a Typhoon last week.\n\nIn a speech this morning he'll compare the flight to\nto his leadership of the Tory party: \n\n"I hauled the joystick right the way back and we did a loop the loop..."\u201d
People speculated it might have been motivated by Ellwood's support for leadership hopeful Penny Mordaunt, and his sustained criticism for Johnson but government loyalist rebuffed these claims.
But the whips’ office confirmed the next day that the MP would be “temporarily unsuspended” so he could vote in the contest, before having the whip suspended again by the end of the afternoon.
That's something, then.
6. Used his last PMQs to call Starmer a "plastic bollard"
You might think a leader would use one of their final commons appearances to talk about what they have achieved, or to give advice for the future.
It is, after all, a historical moment.
But Johnson used his final PMQs to call the opposition leader a "plastic bollard" and when he left the chamber said: "Hasta la vista".
7. Played with grenades
Johnson visited Ukrainian troops training in Yorkshire in late July and joined in the training.
He was even filmed throwing a grenade and pictured playing with guns.
\u201cThis week I visited Ukrainian troops being trained by British Armed Forces in North Yorkshire. \n\nThe UK is committed to doing all we can to help Ukraine continue to repel Russian aggression.\u201d
