I remember years ago when someone posted a compilation video of mud scenes that were gathered online and made into one video.

A portion of that video featured two young ladies running or walking along a path beside a creek or large ditch of water. They got to a point in the path where they jumped into the water, but it turned out that it was only shallow water over a deep and very dark muddy bottom. The mud got all churned up making the women muddy.

I have searched over the years but never found this on YouTube, but I think that was where the original came from. Part of the problem was that it is not in English, so search terms such as 'mud' or 'shallow creek' don't bring anything up because their description of the video was in another language.

Does this ring a bell with anyone?
