A husband, his wife, and their nine children are waiting at the bus stop. A blind man joins them later.
When the bus arrives, only the wife and the children can fit on it because it’s overcrowded.
So, the husband and the blind man decide to walk.

As they walk, the husband becomes annoyed by the tapping sound of the blind man’s stick on the sidewalk and suggests, “Why don’t you put a piece of rubber at the end of your stick?
That tapping sound is driving me crazy.” The blind man retorts, “If you had put a rubber at the end of YOUR stick, we’d be riding the bus, so shut the hell up.”
