There was a bit of pre-match banter of course - this one seems legit, given the recent news about Mars, right?
Not everyone was quite getting into the spirit of things once the match kicked off though.
Nerves were on a knife-edge...
Then, at 3-3, Australia's Bernard Foley went over for the first try.
Another massive blow to England's motivation soon followed...
As England laboured to break down the Aussies, English fans started thinking outside the box.
Tensions were rising inside and outside Twickenham.
One Aussie fan here breaking all pub etiquette. Sitting in one chair, while using a separate stool on which to rest his beer. #ENGvAUS— Craig McCulloch (@craigmcculloch) October 3, 2015
There was a bit of a lull, so the classics started coming out

Another Foley try after 35 minutes - and the English rugby players weren't the only ones feeling it.
Some were giving up already...

We were bound to fail as soon as Inverdale was named as the ITV Anchor. Remarkable. #ENGvAUS— TweeterAlliss (Parody) (by Jove) (@TweeterAlliss) October 3, 2015
Of course, it wasn't just the Aussie fans that were happy at half-time.
Every oppurtunity for a laugh was taken.

London Fire Brigade don't miss a trick!
It was all too easy for Australia.
Finally a breakthrough for England as Anthony Watson goes over.
Suddenly things were looking up again for the England fans.
Farrell has the cold dead eyes of a serial killer. Bet he did his own patio. #ENGvAUS— Dai Lama (@WelshDalaiLama) October 3, 2015
It didn't last long.
No matter the question, the answer is probably not "37 year old Nick Easter" #ENGvAUS— Scotty Stevenson (@sumostevenson) October 3, 2015
An Owen Farrell kick then brought England to within seven points - 13- 20. But he was later sin-binned, and the heads dropped again for England.

The laughing at England had already begun...
Tv3 rubbing it in so much I'm actually crying laughing 😂 #ENGvAUS— Saz (@Suraaahh) October 3, 2015

It would be small minded and juvenile to make fun of England now. So let's do that... #ENGvAUS— David McCullagh (@mcculld) October 3, 2015
... before the the nail in the coffin - a try from Matt Giteau.
Let the search for a scapegoat ... BEGIN!
