For our engineer friends here..

A group of blondes in a class at the University of the Pacific 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!"
