pee fly don't bother me.

"A fly in the urinal - what does it make you think of? Dirty? Disgusting? Obscene? Tasteless? It is actually an example of excellent usability. Dutch manufacturers realized that a fly painted on the porcelain of a urinal nearly always became a "target" for men using the facility. And the fly is positioned in precisely the right place for minimal spillage or splashback." via worldusabilityday.org.
