An Englishman, Irishman and Scotsman are driving in the desert, when all of a sudden smoke pours out from the bonnet and their jeep breaks down.
"B*llocks" shouts the Englishman, "what are we going to do now?!!"
Knowing a bit more about cars than the other two, the Scotsman decides to take a look, and decides that nothing can be done.
"Well I don't know about you two" says the Scotsman, "but I'm outta here. There's no way I'm staying in this place to die!" And with that, he gets his stuff together, and starts walking off into the distance.
"Hang on!" shouts the Englishman, who gets HIS stuff together and runs after the Scot.
The Irishman thinks about it for a minute, before deciding what it is he should take with him. Upon doing so, he follows the other two.
Five hours later, and a jeep appears from the distance with a friendly face at the wheel.
"I bet you're glad I found you!!" exclaimed the jeep driver as he got closer.
"Sure are" replied the Englishman, "though we would have been ok for a while yet"
"Oh, why's that?" asked the driver.
"Well" said the Sotsman "I've got loads of drink. So we would have been ok if we got thirsty"
"Yes," said the Englishman "and knowing that, I have brought lots of food and medical supplies"
Impressed, the driver turned to look at the Irishman.
"Why the hell have you brought a car door with you?!!" he exclaimed, looking very puzzled.
"Oh, that's easy" replied the Irishman. "It's in case we get hot, we can wind the window down."
