Why do you get an itch on your back you just can't reach ...........
Why does the phone ring when you are making pastry?
Why does nobody come to see you when your house is nice and tidy?

There are hundreds of these little mysteries, lets hear some more .......

Why do banks only agree to lend money to people who can demonstrate that they do not need it ?

Incidentally, I have an answer to the snow plough question.
I know the (erstwhile) snow plough driver. In bad weather, he drove home in the snow plough and cleared the road on his way to work the next morning - until the rules were changed, forbidding him to take the vehicle home at night. He subsequently had to battle his way in in his car and then take the plough out when he got to work, thus delaying ploughing the road for approx. 2 hours. Much better !
