... Closest I've come to this is e.g. uploading an image by [[:en:User:Arkady Rose]] (my girlfriend) to Commons because she can't be bothered creating Yet Another Login. I uploaded it myself and said it was by her and put there under copyleft-self (dual GFDL and CC-by-sa) with her permission.
And then there's the related case of photographs taken "under direction" (my camera, my idea, but you held it and pushed the button). This has a sort of "work for non-hire" feel to it, and I'm sure it's been discussed at length, too. I mention it now because I just came across an amusing example: [[Image:Thisisspinaltap.jpg]]. Summary (by [[User:Brainhell]]): "this is my picture of me getting a spinal tap".
