Don't Smoke

But if you must, this no smoking sign acts as a handy ash tray.


And, whilst we are on the subject, some of the traffic lights over here have four lights, Green (no surprise there), Amber (Orange/Yellow, whatever), Red and, oh, yes another Red. As one red light seems to mean "Keep going if you aren't actually going to hit anything (probably)" then maybe two red lights means something like "Even if the road is clear, STOP, please".
