This is a story about a husband and wife who are waiting at a nearby bus stop with their nine children. Shortly afterwards, a blind man joins them and decides to wait for the bus as well. When the bus arrives, they find it overloaded with passengers and only the wife and the nine kids are able to fit onto the bus.
So the husband and the blind man decide to walk to their intended destination. 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 really 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."
