Practical jokers were at work at Merchant Taylors’ School, Moor Park, during the weekend.

When boys arrived at school on Monday morning, they found a yellow plastic pot neatly balanced on top of the 40ft-high flag mast. In one quadrangle a flagstone had been removed and a swinging sign advertising a popular beverage was in its place.

The authorities found it difficult to remove the sign – and quite impossible to reach the plastic pot.

In desperation, the fire brigade was called and the receptacle lowered to safety.
