A group of blondes in a class at a local University were given the assignment to measure the height of a flagpole. So they went out to the flagpole with ladders and tape measures, and they�re falling off the ladders, dropping the tape measures - the whole thing was just a mess.
An engineering student comes along, sees what they�re trying to do, walks over, pulls the flagpole out of the ground, lays it flat, measures it from end to end, and then gave measurement to one of the blondes and walked away.
After the engineer had gone, one blonde turned to another and laughed. "Isn�t that just like a dumb engineer? We�re looking for the height, and he gives us the length!"
