Getting married should be one of the most special days of your life. That's why people end up freaking out for months beforehand, blowing their life savings to make it memorable and generally panicking about things going wrong. Like the music you've picked suddenly stopping to be replaced by... well, just have a listen.
As you can hear, that's exactly what happened to this Brazilian couple. The bride was walking down the aisle of the church to Felix Mendelssohn's wedding march when the music abruptly ended and the loud sound of a woman's sexual groans suddenly filled the church.
And you know churches are designed to have the best acoustics, so the 'ooohs' rang loud and clear for a few seconds until it was turned off. People in the congregation tried to suppress their laughter but you can hear a few giggles and snickers rippling around the room.
Even worse is the fact that - although you can't see her face - you can tell that the bride is absolutely devastated and horrified at what's happened. As you probably would be, to be fair.
According to the Mirror, friends of the couple said they had downloaded the clip in an attempt to save money by not hiring actual musicians.
The problem is that they didn't listen to the clip all the way through. Which, as we said, given that your wedding day is meant to be one of the most special days of your life, they probably should have.
At the same time, you don't expect someone might have inserted sex noises into the middle of one of the most widely used and well-known pieces in the history of classical music.
To that extent, we kind of have to admit that it's a pretty genius prank, if also a rather cruel one. Still, if the couple ever get married again, they'll know to listen to whatever recordings they plan on playing all the way through. As will everyone who's seen the video.
Thankfully, friends of the couple say that the day wasn't ruined and everything else about it went off without a hitch. And, once they get over it, the couple will have a hilarious story to talk about for the rest of their lives.
