An aged farmer and his wife were leaning against
the edge of their pig-pen when the old woman
wistfully recalled that the next week would mark
their golden wedding anniversary.

"Let's have a party, Homer," she suggested.
"Let's kill a pig."

The farmer scratched his grizzled head. "Gee,
Ethel," he finally answered, "I don't see why the
pig should take the blame for something that
happened fifty years ago."
