An old man gets on a crowded bus and no one gives him a seat. As the bus shakes, the old man cane slips on the floor and he falls.

As he gets up, an 8 year old kid, sitting nearby turns to him and says, 'Sir if you put a little rubber thingy on the end of your stick, it wouldn't slip.'

The old man Snaps back, 'Well, Sonny, if your Daddy did the same thing eight years ago, I'd have a bloody seat today!!!'
