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 down.

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!”
