Deer
This was a conversation I overheard between Winston and Andy.
Winston: Why are you building the fence?
Andy: So the deer don't come in
Winston: Why do the deer come in?
Andy: To eat the flowers
Winston: Why do they eat the flowers?
Andy: Because they are hungry
Winston: Why are they hungry?
Andy: Why does Winston get hungry?
Winston: Pauses and thinks very hard and then replies "but I don't eat flowers"
