Another one from my email archive:

As a lorry driver in Essex stops for a red light, a blonde in her car pulls up alongside.

She jumps out of her car, runs up to his lorry, and knocks on the door. The driver lowers the window, and she says

"Hi, my name is Tracey and you are losing some of your load."

The lorry driver ignores her and proceeds down the street. When the truck stops for another red light, the girl again catches up. She jumps out of her car, runs up and knocks on the door. Again, the lorry driver lowers the window.

As if they've never spoken, the blonde says brightly, “Hi, my name is Tracey, and you are losing some of your load!"

Shaking his head, the lorry driver ignores her again and continues down the street.

At the third red light, the same thing happens again. All out of breath, the blonde gets out of her car, runs up, knocks on the cab door. The lorry driver lowers the window. Again she says "Hi, my name is Tracey and you are losing some of your load!"

When the light turns green, the lorry revs up and races to the next light. When he stops this time, he hurriedly gets out of the lorry, and runs back to the blonde.

He knocks on her window, and as she lowers it, he says

"Hi, my name is Kevin and I'm driving a f*****g gritter!"
