BBC Sport, France, Tuesday 6th June - In a repeat of the classic of 2003, Justine Henin was due to meet Serena Williams on the clay at Roland Garros, in a highly anticipated Ladies Quarter Final.
However, before the match could get underway, the heavens opened, and within minutes the clay courts were under more than 4 feet (48"/120cm/1200mm/1.2m/1.33333 yards) of water.
Ms Williams came out from her changing room to check the courts, and then much to everyone's surprise, out came Ms Henin on a one-man (or in this case one-woman) catamaran.
The crowd started to giggle, Ms Williams turned around, and Ms Henin literally sailed past her, waving and grinning rather inanely.
"Henin just sailed past and Williams was powerless to stop her" commented one rather bemused onlooker.
When play finally got underway later on in the day, Henin defeated Williams in straight sets, 6-4, 6-3.
