A husband and wife are waiting at the bus stop... with them are their 12 children. A blind man joins them after a few minutes. When the bus arrives, they find it is overloaded and only the wife and her 12 children are able to fit on 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 the stick, that ticking sound is driving me crazy." The blind man replies, "If you had put a rubber on the end of your stick,we`d be on the bus right now, so shut the hell up!"
