Blind man standing at the bus stop with a man, his wife and 7 kids. The bus stops and the driver says "Sorry, room for 8 only". They agree that the wife and kids get the bus and the other two walk into town with the husband guiding the blind man. After about a half mile the husband says, "I'm sick of the constant tap tap tap of your stick on the pavement, why don't you fit a rubber end". The blind man replies, "If you'd fitted a fucking rubber end on your stick, we'd be on that fucking bus."
