As retold by Bruce Lowitt

Two men, strangers, seated side by side on a train.

The old man moans, "Oy, am I toisty."

A few minutes go by.

Now, a little louder, "Oy, am I toisty."

A few more minutes.

Now, with real suffering, "OY, AM I TOISTY!"

The younger guy decides enough already. He goes to the dining car, brings back a glass of water, gives it to the old man and says, "Here, drink this."

The old man drinks it and, after a few minutes of silence, moans: "Oy, Vas I toisty."
