Parachutist

An English parachutist and an Irish parachutist were arguing about who
was best at folding a parachute. Unable to resolve their dispute on the
ground, they decided to go up in a plane and judge by the mid-air
performance of their parachutes.

The Irishman jumped first, pulled his cord, and started floating down
towards the earth.

Then the Englishman jumped, pulled his cord and nothing happened; he
pulled his safety cord - nothing. In a matter of
seconds he whizzed past the Irishman, plummeting like a stone.

"Oh," shouted the Irishman, yanking off his harness, "so ya wanna race,
do ya?!"
