A good friend of mine called in fatigued for a red-eye going home on the last day of the trip. They were doing construction outside the SFO hotel the whole day before the red-eye and he simply couldn't get any rest that day before the flight. They simply deadheaded in a pilot from SLC, the flight left an hour or two late and he deadheaded home the next day. He was asked to write an ASAP or FCR, can't remember which and didn't hear anything from it.
