We all have bad days at work, but sometimes, things can go more wrong than you could ever imagine.
And for these referees, their faux pas happen under the watchful eyes of thousands - if not millions - of people.
So next time you spill coffee all over your paperwork, spare a thought for these five officials who once had a whole stadium explicitly berating them for what were, admittedly, awful decisions.

JORGE LARRIONDA – GERMANY V ENGLAND, 2010
Where else to start than with one of football's biggest refereeing blunders?
Article continues below
Trailing 2-0 to Germany at the 2010 World Cup, England pulled a goal back through Matthew Upson before Frank Lampard superbly chipped the ball over Manuel Neuer to level it up.
Cue ecstasy - everyone knew England had equalised.
Everyone except, of course, the Uruguayan official (and his trusted assistants), who judged that the ball had not landed several feet over the line. And just like that, the Three Lions’ World Cup dreams infamously went up in smoke.
ANDRE MARRINER – CHELSEA V ARSENAL, 2014
Ever forgotten to put your contacts in?
That must have been what happened to Premier League ref Marriner when, after Arsenal’s Alex Oxlade-Chamberlain handled the ball in the penalty area, he proceeded to dish out a red card to teammate Kieran Gibbs instead. Oh dear.
The guilty party (shown above) even admitted his wrongdoing, yet Marriner stuck to his guns. Arsene Wenger's side went on to lose 6-0, but the game will forever be remembered for one particular incident.
MARTIN HANSSON – FRANCE V REPUBLIC OF IRELAND, 2009
At the time, Hansson probably became the second-most hated person in Ireland - and beating him to top-spot was Thierry Henry.
The Frenchman’s blatant handball went unseen by the Swedish officials as Henry set up William Gallas for a vital goal in a World Cup qualifying play-off.
The Irish were eventually knocked out and spent the World Cup watching in front of the telly. Ouch.
GRAHAM POLL – CROATIA V AUSTRALIA, 2006
There must be something about international football that turns referees’ brains to mush.
You have the infamous ‘Hand of God’ controversy, or when German ‘keeper Harald Schumacher went unpunished despite almost killing France’s Patrick Battiston four years before Maradona's antics.
But without wanting to evoke any further pain amongst the English, let’s all laugh at one Englishman instead.
Referee Poll was overseeing an ill-tempered clash and had already sent off two players before booking Hertha Berlin defender Josip Simunic for a second time - but then failing to show him a red.
Poll didn't pass up the next opportunity to dismiss when the defender unwisely continued to complain after the final whistle, showing the Croat a third yellow card.
STUART ATTWELL – WATFORD V READING, 2008
Only the referee could tell you what he was doing here. Nearly eight years on, everyone else is still at a loss.
With the ball bouncing dangerously around the Watford penalty area, the Hornets eventually cleared, yet the inexperienced Attwell - just 25 at the time - pointed to the centre circle after his linesman had signalled a goal.
The 'ghost goal' was credited to the desperately unlucky John Eustace, who possibly has the craziest own goal ever on his CV.
