Kidding, : )

Where was this that you first heard it, Europe? It is such a widely used
expression, it isn't even challenged. Not that I am endorsing it. I
couldn't use it myself. People would think I was just watching some war

I would think anybody hearing it for the first time, would hear the word
"no" in there and wouldn't think that meant the traffic was sighted,
doh, im mean "in sight".
