A photograph taken in a gym went viral after hundreds of users tried to figure out what exactly was appearing in the image.
At first glance, the strange figure on a bench looks like some kind of abstract drawing or even a curious work of art. However, the reality turned out to be far less artistic: it was a huge sweat stain left by a person who used the equipment and left without cleaning it.

What stood out most was the level of detail that was left marked on the surface, something that triggered an avalanche of jokes on Reddit. “So much detail, this guy sweats in 4K or something!”, wrote one user. Another commented: “Looks like SpongeBob was working out again”.
The post racked up thousands of reactions from people who were horrified, amused, and surprised by what they considered one of the most obvious sweat marks they had ever seen in a gym.
And you, would you have figured out what it was at first glance?
