How about another joke, gluey?
A South African, an Englishman, an Australian, and a Kiwi are all flying over the Tasman Sea in a light plane. Suddenly, the plane begins rapidly losing altitude. The pilot comes into the passenger cabin and says "guys, I don't know how to tell you this, but the only way I can save the plane is if one of you jumps out."
They all look at each other. The South African summons up some courage, gets to his feet, declares "I'm doing this for my country!", and jumps out.
The plane initially stops dropping, but then plummets even faster. The pilot returns to the passengers. "I don't know how to tell you guys this," he says, "but another one of you will have to jump."
The Englishman, inspired by the South African's patriotism, says "I'm doing this for my country!", and jumps out.
Again, the plane initially stops descending, but then plummets once more. The pilot returns to the passengers. "Guys, I can definitely save the plane, but only if one more of you jumps out."
The Aussie and the Kiwi look at each other. Suddenly, the Kiwi exclaims "I'm doing this for my country!", and pushes the Australian out.
