Put A Rubber On The End Of Your Stick

A husband and wife are waiting
at the bus stop, with them are
their 8 children. A blind man joins
them after a few minutes. When
the bus arrives, they find it
overloaded and only the wife and
her eight children are able to fit
in 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 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
would've put a rubber on the
end of YOUR stick, we'd be sitting
in the bus.
