A husband and his wife are waiting at the bus stop along with their nine children. A blind man joins them after a few minutes. When the bus arrives, it is overloaded and only the wife and nine kids are able to fit into the bus. So the husband and blind man decide to walk. After awhile, the husband gets irritated by the ticking of the stick of the blind man as he taps it on the sidewalk, and says to him, "why don't you put a piece of rubber at the end of your stick? That tick, tick, ticking , should is driving me crazy". The blind man replies, "If you had put a rubber on the end of your stick we'd be riding the bus, so shut the hell up!".
