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, and they
fell off the ladders, dropped the tape measures and pencils -- the
whole thing was just a mess.
An engineering student comes along and
sees what they're trying to do. He walks over, pulls the flagpole
out of the ground, lays it flat, measures it from end to end, and
then gives the measurement to one of the blondes and walks 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!"
