I owed my friend George $25. For about three weeks I owed it to him.
The whole time I had the money on me---he didn't know it. Walking
through New York City, 2:30 in the morning, we got held up. He said,
"Gimme all your money." I said, "Wait a minute." I said, "George,
here's the 25 dollars I owe you." The the thief took a thousand dollars
out of his own money and he gave it to George. At gunpoint he made
me borrow a thousand dollars from George.
