A group of blondes in a class at Texas A&M University were given the assignment to measure the height of a flagpole. So they went out to the flagpole with ladders and tape measures. They fell off the ladders, dropped the tape measures and pencils. The whole thing was just a mess.

An engineering student came along and saw what they're trying to do. He walked over, pulled the flagpole out of the ground, laid it flat, measured it from end to end, and then gave the 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".
