A husband and wife are waiting at the bus stop with their nine children. A blind man joins them after a few minutes.
So the husband and the blind man decide to walk.
After a while, 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 ticking sound is driving me crazy.” The blind man replies, “If you had put a rubber at the end of YOUR stick, we’d be riding the bus, so shut the hell up.”
