This reminds me of a vignette on Car Talk. The new owner of a used car found several hundred dollars hidden under the seat. The Car Talk guys said it was good karma to give it back. "However," they said, "if the amount turns out to be several thousand dollars, call us back and we will give you a different answer!" @:-)

I once had a large erroneous posting. I just waited and it went away by itself, so I never had to answer the question.
