Old Man on the bus

     An old man gets on a crowded bus and no one gives him a seat. As the 
     bus shakes and rattles, the old man's cane slips on the floor and he 
     falls.
     
     As he gets up, a seven year old kid sitting nearby, turns to him and 
     says, "If you put a little rubber thingy on the end of your stick, it 
     wouldn't slip."
     
     The old man snaps back, "Well, if your daddy did the same thing seven 
     years ago, I would have a seat today."
