I remember elementary Catholic school, 20 years ago, where white shirts, and black pants was the uniform of the day, so when come the last class on Friday, stealing what ever chalk was left on the board, was the thing to do.
We had "chicken fights" on the walk home, where one guy on the back of another would try and do as much damage as he could.
The white chalk would wash out no problems, so mom wasn't mad.
Egoism, bumps and bruises ...
That and being bad that day in class and you could be penalized by having to say after and "clap the erasers", which meant you'd miss the fights.
