This happened when one of my uncles was playing. There was a guy on his team who was very small in fact apparently he spent some time as a jockey. Anyway his school were playing one day and his mum came to watch him. She was really posh. So her son got the ball for the first time about an hour into the match and promptly got tackled. Of course a ruck was formed and a lot of people ended up on top of him. The suddenly the mum ran on to the pitch screaming started slapping players with her handbag and pulled her son out of the ruck to the sideline.
