The gorgeous bride was wearing white, the sun was shining and all their friends and family were looking on.
In fact everything was going well until the ring bearer was asked to come forward to present the ring to the priest.
In a video that has become one of the most-visited clips on YouTube, the unfortunate man trips over his own feet as he mounts the makeshift stage.
In a spectacular whirl of flailing arms and legs he falls flat on his face and somehow manages to shove the bride and the priest into the nearby swimming pool.
The congregation gasps and people shout out 'Oh my God' as the shocked bride and clergyman are left floundering in the swimming pool.
One rather mean-spirited guest just about manages to stifle a snigger as the drenched pair stand dripping in the water.
Almost 100,000 people had watched the video on YouTube this morning.
Some cynics who have watched the video have left comments suggesting that the accident is not quite as genuine as it first appears and that it's more a bid for notoriety in the manner of 'You've Been Framed'.
