Gibraltar started bilateral talks with Spain because it needed to make sure its people are safe after Dec 31 and the UK refused to negotiate arrangements, wanting to leave everything to brinkmanship with the EU in October.
Johnson wishes Gibraltarians a happy national day by telling them to to look forward to Brexit, which 96% of them voted against.
Gibraltar is 7km² with a population of 33k, it depends on Spain for food, health services and mobility. Change can be scary, Johnson says from Downing St, like an HR manager explaining over Skype that redundancy at 55 is an opportunity to be seized.
Gibraltar, which has no MP to defend it in Westminster and no MEP since January, is exploring joining the EU Customs Union for the first time and possibly even Schengen. In that context, this looks a bit threatening from Johnson. Happy National Day and do as you're told.
Of course, you can decide to become Spanish, Johnson says. So there's the choice, you chaps Gibraltar: join us in burning everything down or get lost. And Happy National Day.
As always, a picture of Gibraltar's geographical position is needed until the last British person stops thinking it's an island, which will be never.
