Packed Bus

The husband and wife were waiting at the bus stop with their nine children. A blind man joined them after a few minutes.
When the bus arrived, they found it overloaded, and only the wife and the nine kids were able to fit onto the bus. So the husband and the blind man decided to walk.
After a while, the husband got irritated by the ticking of the stick the blind man used. He turned to him and said, “Why don’t you put a piece of rubber at the end of your stick? That ticking sound is so annoying.”
The blind man replied, “If you had put a rubber at the end of YOUR stick, we’d be riding the bus, so shut the hell up.”
