Dennis' Revenge

Joss' mower, Dennis, is to be semi retired soon and replaced by a new Allett cylinder mower. I was walking across the Nuffield Lawn earlier today when I came across Dennis and it looked like he had mown over Joss, all that was left was his gloves sticking out from beneath the large roller.
It looked like Dennis had has his revenge until Joss appeared from the otherside of the lawn.
