#34: Do Not Stand on the Toilet
This bathroom sign warns: “Please do not stand on the toilet. It could break and you could be injured.” The bold black letters make it sound like a life-or-death matter, while the little stick-figure illustration drives home the point in unintentionally hilarious fashion.

The comedy comes from how oddly specific it is. Clearly, enough people tried balancing on toilets that management had to step in. Whether it was curiosity, cultural habit, or sheer mischief, the result is this unforgettable reminder that porcelain was not designed for gymnastics.
