An Aussie, a Yank and an Irishman are in a cell awaiting a firinq squad. The Aussie is called out first and is lined up against a wall. As the soldiers raise their rifles he shouts out "earthquake". The soldiers drop their rifles and run away whilst the Aussie jumps over the wall and escapes.

After the soldiers regroup they call out the Yank and place him in front of the wall. He then shouts out "tornado". The soldiers drop their rifles and flee whilst the Yank jumps over the wall and escapes.

The Irishman says to himself "Ah, I see how its done. All I've got to do is shout out a natural disaster and as the soldiers run away I can escape over the wall".

The soldiers grab the Irishman and place him in front of the wall. As the soldiers point their rifles at him he grins and shouts "Fire".
