Farmer John was taking his cow and it's new born calf to sell in the auction. On the way farmer John got robbed by thieves, who beat him up, stripped him of his clothes and tied him to a tree. Then taking the mother cow and John's clothes, the thieves escaped. They, however left the new born calf behind.
Poor farmer John suffered as for two days, he stood tied to a tree, stark naked and hungry. Fortunately, on the third day, some neighbors happened to pass by. They recognized John and untied him. When they did, farmer John picked up a huge stick and started bashing the calf with it.
"Why are you thrashing the poor calf?, his neighbors asked?
To which farmer John replied, "I had to tell this beast for the past two days repeatedly that I am not your mother!, I am not your mother!"
