Hmm!

Everything is not always as it seems. Several years ago, after having my left knee replaced, I was hobbling down the sidewalk to the Doctor's office for a post surgical checkup. As I was walking I met a man who was kind of dragging his foot on the ground as he walked toward me. To be sociable I pointed to my left knee and said, "Left knee replaced back two weeks ago, you?" He nodded and said, "Dog poop, back about twenty feet."
