The Farmer and the Dell

While watching MSU beat up on Northwestern today, Gerrit spent a lot of time playing with his animals that go with his John Deere toys. He took all of them and lined them up on the chair that I was sitting in, then he would walk across the room and admire his work, come back and knock them down and start the process over again. I thought it looked pretty cute how he lined up all the animals and the farmer . What is 'the dell' in that song anyways?????
