Something I say would be atleaste useful for RP servers. There would be a bar for the bathroom. The more the bar is filled up, the slower your person will be. If the bar fills up all the way, well, I think you know what happens. This would happen with a event that fills up the bar a certian % . I really don't care if you call this stupid, it's just an idea.
EDIT: And if you stand on a special brick caleld "Pee", you go pee!
There, now go away FSDFD
