In 2006, it was a famously dodgy lasagna that was suspected to have poisoned the Tottenham Hotspur squad, helping Arsenal to clinch qualification for the Champions League.
On Sunday, it appeared that outside influences were at work once again, after stand-in West Brom goalkeeper Marton Fulop was at error for all three Gunners goals, as Arsene Wenger's side again ensured they finished above their north London rivals with a 3-2 victory at The Hawthorns.
After securing third place, and with it participation in Europe's top tier competition for the 15th consecutive season, it's difficult to imagine how an under par Arsenal would have ever won this match against the Baggies, had first choice stopper Ben Foster not aggravated a groin injury in training the previous day.
But, Fulop froze on what was his first Premier League appearance for two years, and two of his three mistakes that led to goals will go down as serious contenders for blunder of the season.
His first mistake arrived after just four minutes. James Morrison had reacted quickly to dispossess Robin van Persie just inside the West Brom half, with the ball appearing to cannon harmlessly towards the edge of the penalty area.
But, rather than kick the ball to safety, Fulop inexplicably hesitated and tried to wait until he could use his hands. Yossi Benyaoun sensed the panic, and was quick enough to get his foot to the ball and then roll it into an empty net.
West Brom responded positively and hit back with two quickfire goals from Shane Long and Graham Dorrans - the first of which had more than a hint of offside. But, the Gunners still went in level at the break after Andre Santos fired a precise shot inside Fulop's near post.
With news coming in from White Hart Lane that Spurs were cruising 2-0 against Fulham, Arsenal knew they had to press forward in search of a winner.
It came when Van Persie's corner was met by the fist of Fulop, who, somehow managed to skew his attempted punch back towards his own goal, only for it to be met on the volley by Laurent Koscielny, who smashed into an unguarded net.
Had it not been for Fulop, who was later described as "devastated" by assistant head coach Keith Downing, Arsenal may have been forced to reflect differently on the success of their season, and West Brom could have given England bound manager Roy Hodgson a perfect send-off.
In homage of Fulop's calamitous performance, GiveMeFootball has assembled five of the best worst goalkeeping errors...
Robert Green: June 2010
In England's opening Group C game of World Cup 2010, the West Ham United goalkeeper gifted the USA a draw after letting a tame Clint Dempsey shot squirm under his legs and into the net.
Massimo Taibi: 1999
The Italian goalkeeper lasted just four games at Old Trafford after a £4.5million switch from Venezia.
Taibi's most famous howler came in a 3-3 draw against Southampton when he bent down to scoop up a mishit grass-cutter from Matthew Le Tissier only for the ball to go through his grasp, between his legs and in.
Peter Enckleman: 2002
Mistakes are the last thing you want in a derby. Especially if it's the first Second City showdown for 20 years.
With Aston Villa trailing 1-0 to local rivals Birmingham City, Olof Mellberg threw the ball back to Peter Enckleman, who miscontrolled into the back of his own net.
Shay Given: 1997
Dion Dublin booked the former Newcastle United goalkeeper's permanent place in the countless football blooper programmes with this comical goal.
Given dropped the ball while the Coventry City striker was still behind him, and he quickly took advantage by rolling the ball into the empty net.
The 36-year-old is now known as 'the only Irishman who doesn't know where Dublin is'.
Jerzy Dudek: 2002
The Polish stopper gifted Diego Forlan the opening goal in Manchester United's 2-1 victory over Liverpool at Anfield.
Jamie Carragher's backwards header slithered through Dudek's palms, then his legs before falling into the path of the Uruguayan, who then beat the Reds stopper three minutes later with a highly stoppable shot that crept inside the near post.
