For those who might mistake that hashtag for 'Come on you Saracens', this happened at Stadium MK on 25 April.
We're just 10 minutes away from kick-off, the teams are going through the last of their warm-ups and Franklin's Gardens is filling up nicely. It should be a cracking atmosphere by the time we get under way.

And flanker Tom Wood says they must use that to their advantage to book another trip to HQ this afternoon.
"We've been there and won it and I know what it feels like and I just want to repeat it," he told BBC Radio Northampton.
"We've got to make sure we show the same level of hunger that we did in the final and semi-final last year."

But Saracens director of rugby Mark McCall said his side would not be intimidated by the inevitable white-hot atmosphere inside Franklin's Gardens this afternoon.
"We have got a squad who don't mind being on the road and kind of relish hostile atmospheres," he told BBC London 94.9.
"The atmosphere we faced when we played Clermont in the Champions Cup was something very special.
"Having been through that and played quite a decent game that day, I don't think anywhere else will have big fear for us."
Northampton Saints on Twitter:, external The last game... #EndOfAnEra Let's give the Sturtridge a noisy send-off!
Image source, @SaintsRugbyThe famous pavilion, in situ at Franklin's gardens for nearly 50 years, is being demolished this summer to be replaced by a new stand at the north end of the stadium.
So, it's Bath v Leicester at 17:00 BST but with all the stellar names in those Northampton and Saracens line-ups, the appetiser to that game isn't too shabby either.
It's only a repeat of last year's final, which Saints won in the most dramatic of fashions thanks to Alex Waller's try in the last minute of extra-time.
Image source, Getty ImagesAfter resting their star names for the trip to Leicester last week in their final league game of the season, Northampton revert back to the same 23-man squad that beat London Welsh a fortnight ago.
England stars Dylan Hartley, Courtney Lawes, Tom Wood and Luther Burrell are among those to return to the side that lost at Welford Road.
Image source, Getty ImagesSaracens wing Chris Ashton, who scored four tries in the win over Welsh that secured a play-off spot last Saturday, is only fit enough to start on the bench after illness. There's also a late change among the Sarries replacements as Jared Saunders comes in for the ill Schalk Brits.
But there are starts for England centre Brad Barritt and scrum-half Richard Wigglesworth, as well as 20-year-old forward Maro Itoje, who was named in Stuart Lancaster's 50-man World Cup training squad this week.
Northampton: Tuala; K Pisi, G Pisi, Burrell, Elliott; Myler, Dickson; Corbisiero, Hartley, Ma'afu, Lawes, Day, Wood, Clark, Manoa.
Replacements: Haywood, Waller, Denman, Dickinson, Fisher, Fotuali'i, Stephenson, Wilson.
Saracens: Goode; Wyles, Taylor, Barritt, Strettle; Farrell, Wigglesworth; M Vunipola, George, Du Plessis, Kruis, Hargreaves, Itoje, Burger, B Vunipola.
Replacements: Saunders, Barrington, Figallo, Hamilton, Wray, De Kock, Hodgson, Ashton.

It will probably come as no surprise that our early attention is going to be on events at Franklin's Gardens. So before we go any further, let's take a look at today's line-ups.
What an afternoon we have in prospect and we would just love to know how you think it's going to pan out.
Can Northampton overcome Saracens again and reach their third successive Premiership final? Or will it be the Londoners making the short trip to Twickenham?
And what about events at The Rec later? Is this going to be Bath's year or can Leicester make the most of their play-off experience to reach yet another final?
Let us know using #bbcrugby on Twitter.
Later we have a match-up for you steeped in tradition.
Bath against Leicester is one of the oldest rivalries in English rugby, with the two clubs having gone at it hammer and tongs against each other for more than 100 years.
Image source, Getty ImagesIt's one that in more recent times evokes memories of Guscott, Chilcott and Barnes in the Blue, Black and White, and Kardooni, Johnson and Rowntree for Tigers.
Not to mention England fly-half George Ford, who has played for both clubs and will be hoping to lead Bath into the final today. But more of that later.
Here's how the Premiership table ended up after last weekend's final matches.
It was quite a Saturday afternoon as Leicester, Saracens and Exeter battled it out for the two remaining places to join Northampton and Bath in the play-offs.
Leicester's win over a weakened Saints guaranteed their progress, while Sarries edged out the Chiefs on points difference thanks to a big win over London Welsh.
We've got back-to-back games for you this afternoon which promise to pack more punch than Mayweather v Pacquiao.
Image source, AFPNo fewer than 30 of England's 50-man World Cup training squad will be involved, suggesting we should be in for some high quality action as Northampton face Saracens and Bath tackle Leicester.
After 132 games of a gruelling Premiership season, four teams are left standing.
Image source, Getty ImagesTheir target? A place at Twickenham in next weekend's Premiership final.
