Don’t do this
It seems like they have caught people doing all these things or else they would not have bothered putting up a sign. Who in their right mind would do any of the positions that they have displayed here? Did someone really try to dunk their entire body into the toilet bowl in a public bathroom?
We liked the one that depicted a person fishing as if there are any fish to catch inside of that thing. Or maybe there are some fish in there, which is why it would make sense that people would freak out and assume weird positions at the sight of them.
