Flipflops on, towel down
The morning after the Lord Mayor's show, and Chelsea were already flashing their speedy boarding pass in the priority queue at Gatwick.
Even without some of the more bizarre incidents that were to follow, this game felt like it was sat on the beach from the first whistle.
And then, like a passing seagull dropping its load on your Mister Whippy cone, the sky fell in on Chelsea's party.
There was a moment, somewhere around the third goal, where it was possible to feel sorry for the Blues' travelling support.
But up they rose – bouncing and singing 'We won the league!' for half an hour solid.
Nothing can spoil their party now.
Fabregas may have earned the most pointless red card in Premier League history
With nothing for either side to play for, this game kicked off with a carnival atmosphere.
Even the fans had a bit of a love-in, with both Baggies and Blues clapping along to The Liquidator.
But one man wasn't in the mood to party.
With a melee kicking off inside the West Brom box, Cesc Fabregas hoofed a ball into it – bashing the back of Chris Brunt's bonce.
For once, the brilliant Spaniard was let down by his fabulous touch – connecting just as was clearly intended.
The red card that followed was absolutely no surprise – and fully deserved.
And, as the magic man pulled off his mask, there was more than a hint of embarrassment at what he's done.
It'll be a 'What happened next?' question for year to come, and many will see the comedy. But it also came with a totally needless cost...
Chelsea will doubly pay for Fabregas' stupidity
If, as as seems likely, the Fabregas red is adjudged violent conduct – then a three game ban will follow.
And, as bizarre as it may seem to call pinpoint passing a ball into a player's head 'violent conduct', that is about all they've got for it.
So, that's goodbye to Sunderland at home and the trophy presentation; goodbye to the FA Community Shield at Wembley; and goodbye to the first match of Chelsea's 2015-16 campaign for the Spaniard.
But what felt more of a let down than that was the fact that this was supposed to be an opportunity to showcase youth – and notably, Izzy Brown, who grew up within these four walls. Instead, he was limited to a 15 minute cameo.
Fabregas should offer a quiet word of apology to the youngster for his moment of petulance.
Mourinho has made his peace with the fans
In a game where Chelsea lacked heroes on-pitch, there was no such problem in the stands.
In one of the most character-filled performances of recent years, the travelling support were bouncing and singing throughout.
Mourinho has, more than once this season, riled the Blues' support by calling for more – though notably never complaining about the away crowd.
On full time he marched, alone, to the away end – pumping his fists in the air, and holding aloft a single finger, to tell them 'you're number one'.
Let's get this party started
It's all over, but for the lap of honour.
Sunderland, depending on how things go at Arsenal on Wednesday, may have other plans of course.
But Sunday at Stamford Bridge will be champagne time.
