You might have heard that something quite remarkable happened in the Champions League - the record for goals scored in a Champions League match was broken by Borussia Dortmund and Legia Warsaw, who played out an 8-4 result.
With 32 minutes gone, it was 5-2 to Dortmund, so it had most certainly been coming.
But how exactly is one meant to process such a crazy result?
Well, we thought we'd use maths, and the rest of the evening's Champions League fixtures, to help you get your head around the sheer number of goals that flew in at the Westfalenstadion.
Sevilla v Juventus finished 3-1 to the Italian side - entertaining, for sure, but you'd have had to play the game three times over to match the Dortmund game's goal tally.
There were three 2-1 results. First there was Monaco's 2-1 win over Tottenham...
...then Leicester's impressive 2-1 win against Club Brugge...
...and finally, Real Madrid's comeback against Sporting Lisbon.
All decent games, with plenty of tension. But 3 x (2+1) = 9, which means you'd still be one more 2-1 result short of the 12 goals Dortmund and Warsaw put on for the fans.
OK, next up it's the early kick off: CSKA Moscow 1-1 Bayer Leverkusen. That's two goals, so if we take the Westfalenstadion's 12 goals, and divide it by two, we get six. That's six times as many goals at Dortmund than in Moscow. SIX.
Just the one goal in Zagreb, as Lyon's sole away goal earned them three points. That's a third of a goal per point.
Dortmund also earned three points, but with 12 goals, that's a rate of four goals per point. Make sense?
And finally, Copenhagen's 0-0 draw with Porto. You can't multiply 0 to get 12. It cannot be done.
And that means that Dortmund's 8-4 win over Warsaw was infinitely more entertaining - class dismissed.
