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 up.'
