An elderly Jewish woman climbs onto the bus and looks for a seat.

Seeing no open spot, she approaches a teenage girl and says, "If  you knew
what I had, you’d offer me your seat." The girl is taken aback, but she figures
she’ll do the right thing, and she gives up her seat.

The bus is sweltering in the midsummer heat, and the person next to the old lady has a
little battery-operated fan. The old woman looks at him and says, "Oy, if you knew
what I had, you’d let me borrow your fan. The man isn’t sure what to make of that, but
gives her the fan.

A few blocks later, the woman approaches the bus driver and asks him to stop.
"Lady, I can’t stop until my next scheduled stop. You can get off there it’s just a
few more blocks." "Oh," she says, "if you knew what I had, you’d let
me off here."

The bus driver had seen her get the seat and the fan, and figures he should accommodate
her. He stops the bus. The woman gets off the bus and the bus driver shouts after her,
"Hey lady, what exactly is it that you have, anyway?" She turns back and shouts:
"Chutzpah!"
