are driving thru the desert. They brake down and all get out the car to take a look under the bonet.
All 3 take a look and neither of them no wot the problem is or how to fix it.
So the Englishman says "im taking the water from the radiator so wen im walking across the desert trying to get home, i wont die of thirst!"
Then Scotsman then says "well im taking the fan then, so wen im walking across the desert i can spin the fan and get a cool breeze wen i get too hot."
The Irishman has a think and says "Right so, im taking the car door then!"
The Englisman and Scotsman turn to the Irishman and say "Why the hell do you want to carry the car door across the desert?"
To this the Irishman replies "Ah, well wen i get hot, i can wind the winda down!"
