Husband and wife are waiting at the bus stop with their nine children.
A blind man joins them after a few minutes. When the bus arrives, they find it overloaded 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. 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.
