I have never heard the term "Aggie" applied to Cornell, though it has a very wide range of agricultural science. They have always had formidable football teams, despite the attitude of an early president:

On this day in 1873, Cornell president Andrew White refused to let his school's football team go to Chicago to play,since he said 400 miles was far too far for 30 men to travel "just to agitate a bag of wind."
