An Engineer, a Mathematician, and a Physicist were standing around the college flag pole when an English professor happened by. ‘What are you doing?’ he asked.
‘We need to know the height of the flag pole,’ explained the engineer, ‘and we’re discussing the various formulas we might use to calculate it.’
Student, the English professor proceeded to pull the pole from its fitting, laid it on the ground, borrowed a tape measure, and announced, ‘Twenty-four feet exactly.’ He put the pole back where it had been and walked away.
‘English professor!’ sneered the Mathematician. ‘We ask him for the height and he gives us the length.’
