An elderly man gets on a crowded bus. Looking around, he finds that all the seats
are taken and no one offers to give him a seat.

The bus shakes and rattles, and suddenly the man's cane slips on the floor, causing
him to fall.

As he gets up, a thirteen-year-old kid, sitting nearby, turns to him and, with a sneer,
tells him: "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 around thirteen years
ago, I would have a seat today."
