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.'
Next Joke: A punk and an old man were sitting on a park bench
