Firstly, Manchester City passed the 100-goal mark for the season as they saw off a Cardiff side to stay one point behind leaders Arsenal at the top of the Premier League. Cardiff ended the day bottom.
Edin Dzeko's opener brought up City's century of strikes in just 34 games in all competitions, the quickest that landmark has been reached in the Premier League era.
Manuel Pellegrini's had to wait until the 14th minute to score their opener - and even then they were unsure at first whether it would count.
Dzeko swivelled to meet David Silva's pull-back at the near post but his scuffed shot was hacked clear as it bounced over the line and, for the first time in the Premier League, goal-line technology was used to show it had gone in.
That meant the celebrations at Etihad Stadium came in instalments, as some fans took time to realise referee Neil Swarbrick had given a goal. They were then shown the Hawk-Eye replay on the big screens around the ground to prove Swarbrick's decision was correct.
Those same giant screens immediately flashed up the message 'City, 100 goals and counting' but, the next time the ball was in the net, it was Cardiff who put it there.
If those records weren't enough goalkeeper Joe Hart became the first Man City player to record 100 Premier League wins for the club.
