I always remember back when I was in the army and posted to an airforce base. One day I went into town with a mate who was in the airforce during a lunch break in his car.
We were both in uniform and to be honest he was a bit of a speed demon when it come to driving.
Well the inevitable happened and he got pulled over by a traffic copper.
I nearly peed myself when the copper peered in and said "what's the problem wing commander - having trouble taking off are we?"

Luckily the copper was ex army and let him off with a warning because despite speeding it wasn't neccessarily excessive.
I think he was just waiting to use that line and we provided the opportunity.
