Blind Man and the Bus
A man, his wife, and their eight children were waiting at a bus
stop. Not long after, a blind man joins the group.
The bus arrives. The blind man and the husband are forced to
walk because there's just no more room on the bus.
As they walk together, the tapping of the blind man's cane
starts to irritate the other man. Finally, the man says, "You
know, that's pretty irritating. Why don't you put a rubber on
the end of that stick?"
The blind man retorts: "If you'd put a rubber on the end of
*your* stick, we'd both be on that bus."
