Origins
During the Eton Wall game in 1822, the team from Rugby, who were Tom Brown’s Schoolmates, got tired of trying to kick the ball and picked it up and ran away. The Wall Game has continued for the last 183 years without anyone realising there is neither a ball nor an opposing team.

William Webb Foot

Swing low, sweet chariot
Traditional English way of adjusting shorts.

Ruck
Getting your shorts in an uncomfortable position.

Scrummage
Old shorts donated by former rugby players.

Conclusion
Rugby is a game whose rules are too complex to be understood, and so are generally ignored unless the game is televised, when former players are forced to make up a plausible scenario to explain the carnage on the pitch.
