Measurement

A group of Surds were given the assignment to measure the height of a flagpole.

So they go out to the flagpole with ladders and tape measures, and they--re falling off the ladders, dropping the tape measures - the whole thing is just a mess.

A passer-by comes along and 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, gives the measurement to one of the Surds and walks away.

After the person has gone, one Surd turns to another and laughs. What a nut, we--re looking for the height and he gives us the length.
