This moment is so perfectly-timed it might be one of Boris' best blunders yet.
Poor Boris Johnson's latest photo stunt on Thursday (November 19) was ruined in comical fashion when a grumpy commuter he was waving at gave him the finger.
The London mayor was on his bike to unveil the capital's first fully segregated cycle superhighway.
But for the Tory who's been pictured stuck on a zip-wire and rugby-tackling a 10-year-old, the message once again got a bit lost.
The scene was captured as Mr Johnson christened Route CS5 by riding across Vauxhall Bridge.
And the cheeky cyclist wasn't alone.
The MP, who steps down as mayor next year, reportedly shrugged off a volley of abuse from three different commuters during the event.
At the opening of the cycle superhighway, Boris Johnson MP said: "We've brought a bit of Amsterdam to the unlikely environs of Vauxhall - opening up access to huge swathes of south London for safer cycling.
"I've always believed that more Londoners would cycle if they felt safer, and this new route already proves it.
"The astounding rises in cycling through Vauxhall should lay gently to rest any doubts about the need for my new superhighways, the pent-up demand in London for cycling - and the part my cycle lanes can play in taking other vehicles off our crowded streets.
"With London's population growing by 10,000 a month, there are only two ways to keep traffic moving - build more roads, which is for the most part physically impossible, or encourage the use of vehicles, such as bikes, which better use the space on the roads we've already got."
