Medical misdiagnosis

During my physical examination yesterday, my doctor asked me about my daily activity level, and so I described a typical day this way:  “Well, yesterday morning, I waded along the edge of a lake, escaped from   wild animals in the heavy brush, marched up and down several steep rocky   hills, charged through a patch of poison ivy, crawled out a swamp, and   jumped away from an aggressive dog.”   Inspired by my story, the doctor said, “You must be some outdoors man!”   “No,” I replied, “I’m just a shit golfer that plays at PDF!”
