Europe's amazing Ryder Cup win on Sunday masked a massive choke from Team USA, who were 10-6 going into the final day.
In fact, thet were 10-4 at one point.
But they aren't the first team to bottle it. Here are 10 of the best.
10. Rory McIlroy (Masters, 2011)
The young Irishman had a four-stroke lead going into the final day but fell apart between the 10th and 12th holes, carding triple -bogey, bogey, double-bogle. Facepalm.
9. Audley Harrison (WBA heavyweight title, 2010)
Audley was all talk ahead of this fight but managed just one punch as Haye won in three relatively easy rounds (as he had predicted). Harrison was so bad an investigation was carried out.
8. Jana Novotna (Wimbledon, 1993)
Leading 6-7 6-1 4-1, Novotna was at game point to go 5-1 up against Steffi Graff in the final set of the Wimbledon final, but a double fault sparked a huge meltdown. It ended with her crying on the shoulder of the Duchess of Kent as the awards were handed out.
7. England (various penalty shoot-outs!)
As sure as night follows day will England mess up a penalty shoot out. Only have one they prevailed (against Spain in Euro 96, and even then they followed that up with a penalty defeat to Germany).
6. Greg Norman (Masters, 1996)
Looking like Crocodile Dundee in that hat, Norman would have wished he was back in Australia after a final round 78 that handed the title to Nick Faldo, who he started the day six trokes ahead of. Strewth!
5. Chris Webber (NCAA Tournament, 1993)
The Michigan man travelled and then called for a timeout when his team had none left in a crazy few seconds, that handed the NCAA title to North Carolina.
4. Newcastle United (Premier League, 1996)
Magpies boss Kevin Keegan began the implode with his team 12-points clear of Manchester United going into the final furlong, with his famous TV outburst (see below) and his team's confidence was drained. It allowed Ferguson's men to pip them to the title.
3. Jimmy White (World Snooker Final, 1994)
History repeated itself for Jimmy, who had collapsed two years earlier to Stephen Hendry from 14-8 up to lose 10 frames in a row, and in 1994 he missed a routine black to hand the final frame to Hendry. Again.
2. Jean van de Velde (The Open, 1999)
The Frenchman only needed a double-bogey six on the 18th for a shock Open win, a hole he'd birdied the previous two days. But he lost it, finding the rough, the water and the bunker, hitting a triple-bogey seven and losing in a play-off to Paul Lawrie. Scare bleu!
1. Roberto Baggio (World Cup, 1994)
The Juve No.10 single handedly dragged Italy to the final with late winners over Nigeria and Spain in the second round and quarter-final and a double in the semi-final. But he choked in the final, froze during the game and missed the deciding penalty. Oops.
