The first passenger was Thierry Henry he said " I am the worlds greatest footballer the world needs me " so he takes the first parachute and jumps off.
The second passenger was Robert Mugabe he said
" I am the worlds greatest and cleverest leader. The world needs ME." So he takes the third parachute and jumps off.
The next passanger was David Cameron he said " I am the worlds greatest Prime Minister the world needs me" so he takes the next parachute and jumps off.
Now there is only one parachute left and two passengers, Nelson Mandela and a primary school boy. mandela says to the boy "I have lived a rich and full life. I can die, you take the last parachute"
The boy says " No need sir Mr Mugabe the the worlds greatest Prime Minister has jumped out taking my school bag."
