There were these computer science student, an engineering student, a physics student and a meterology student going through the desert in a jeep.

Suddenly the jeep stops and they're left sitting there wondering what happened,

The Eng student pipes up,
" It must be the fan belt thats broken, the engine has overheated , so we'll just have to wait till it cools down, bodge the fan belt and we'll be fine."

The meterology student replies,
"naw, it's not that, its just the ambient heat in this place. It's not allowing the engine to breath correctly, we just have to wait till night time, "

The Physics student replies:
"This is obviously a classic problem of torque. The heat has caused a thermal expansion thereby extending the belt beyond its elastic limit causing capillarity in the water in the radiator"

The computer science student thinks about this for a minute then says,
"yeah, you might be right, but I've got an idea, What say we close the Windows, go out through the Dos and open the Windows again?"
