This is my favorite newspaper correction in recent memory:
A Gannett News Service story about Sen. Joe Biden's appearance on "The Daily Show" incorrectly stated that host Jon Stewart jokingly suggested that someone ought to buy the state of Delaware indoor plumbing. Stewart's reference was to indoor carpeting.
I'm looking forward to more corrections in this vein, such as: "A Gannett News Service story about a man with a duck on his head walking into a bar incorrectly stated that it was the man who addressed the bartender. It was the duck who first spoke. No, wait, maybe it was a woman with a pig under her arm …"
(The original story, complete with alternate punchline, is here.)
