If, like many people, you find yourself bored on the train, and disillusioned with the on-board magazine, advertising snacks and extraneous luxury goods, you can try an ingenius game I devised, Kickback ©:
Try to kick the backrest in front of you as many times as you can in a 10-minute interval, without being chastised by its occupant; then try to beat that score. If they hit you, the timer resets. If they change seat, try to follow. Double points are awarded for subsequent kicks.
An alternative to Kickback © is 'Antimacassar Bandit' ©:
Participants operate in teams, starting at opposite ends of the train, and work progressively through the carriages, trying to 'confiscate' as many antimacassars as possible, whilst avoiding detection by the train company's staff. Posing as ticket inspectors can be an effective way of achieving this; participants can patiently inform the passengers that they didn't specifically express their desire for an antimacassar, when purchasing the ticket. Standard antimacassar-tax is 45p. Those who refuse the surcharge, forfeit their headrest-cover; all perfectly reasonable. At the end of the game [read: train journey], both teams simultaneously present all the captured antimacassars to the independent adjudicator: the ticket inspector, and then run away. He / She determines the winning team by deciding who to chase after. Successful prosecutions against you, by the train companies, are taken as marks of distinction.
