A husband and wife, accompanied by their nine children, wait at the bus stop. Soon, a blind man joins them.
When the bus arrives, it’s too crowded for everyone to board except for the wife and the nine children. Left with no choice, the husband and the blind man opt to walk instead.
As they walk, the husband becomes increasingly annoyed by the sound of the blind man’s tapping stick on the sidewalk. Frustrated, he suggests, “Why don’t you put a piece of rubber at the end of your stick? That tapping sound is driving me crazy.”
In response, 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.”
