Rickochet We had a black lab who was wonderful but we nicknamed her "Meathead."
I had a distant relative who had a black lab that he named "Stupid." He taught that dog (which was no dummy) to do tricks by the wrong names. He would say sit Stupid and the dog would lay down. Then he would say beg and the dog would walk away from him. He had 7 or 8 tricks that he did, all by the wrong names.
