Tottenham were dumped out of the FA Cup by Norwich City on Wednesday night.
After a rather dull 90 minutes, the score was level at 1-1.
Jan Vertonghen netted the first goal inside 15 minutes and it looked like Spurs would cruise to victory, but that wasn't the case.
They failed to score a second and were punished with 12 minutes to play when Josip Drmic forced an equaliser over the line.
Half an hour of extra time passed without incident and penalties were needed to decide the tie.
Cue a masterclass from Norwich goalkeeper Tim Krul.
The Dutchman has a bit of a reputation for playing mind games during a shootout and those were on show against Spurs.
He bounced up and down his line, wasted as much time as possible and even kept leaving the goal to take a drink from his water bottle.
But there was a method to the madness because it's since been revealed that Krul had the names of every Spurs player - and where they were likely to put their penalties - written on his bottle.
Having notes written on a bottle isn't a new trick, goalkeepers have been doing it for some time now.
But there's no doubt it really did help make Krul the hero this time.
He saved two penalties, one from Troy Parrott and the other - the decider - from Gedson Fernandes.
Erik Lamela also missed a spot-kick for Spurs, blasting his effort over the crossbar.
Norwich advance to the quarter-finals of the FA Cup and have been rewarded with a home tie against either Manchester United or Derby County.
Should that game go to penalties, the Canaries will surely fancy their chances again - especially if Krul prepares with a water bottle again.
