An Englishman, an Irishman and a Scotsman were trying to cross a shark-infested
river in The jungle. The Englishman was first to cross and he lost an arm to a
shark. Next The Scotsman crossed and he lost a leg. Finally, The Irishman waded
across The river without a shark laying a tooth on him.
'How did you manage that?' they asked him.
'It was easy,' smiled The Irishman, 'I just wore a tee-shirt with England/or The
World Cup on it. Not even sharks would swallow that.'
