Our football burst one breaktime. Someone had the idea of taking out the deflated inner balloon through the burst seam and replacing it with some large stones.
We then 'accidentally' rolled the ball over towards a group of older bastard kids, knowing that they would try to kick it over the fence.
And it worked. Honestly, it worked. One of them took a good run up, had a huge hoof at the ball, shouted out loud, and hopped off on one leg in considerable pain, and probably saying "ooyah!"
I have never since experienced such complete satisfaction at the entirely successful execution of a plan. We strutted around like five little George Peppards for a week.
