husband,wife and blind man

A husband and wife are waiting at the bus stop; with them are their 8Children... 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! So shut up and keep walking!!!!"
