Link to the original and not some reupload to imgur: http://nedroidcomics.tumblr.com/post/41879001445/the-interne... :)
Though I never quite understood which interpretation was intended:
* Creator shows their work to someone, who goes on claiming it's their own work.
* Someone shows "their work" to the original creator, who then realizes it's actually their work.
I only hope the original author is aware and supportive of the meta-sentiment of the re-upload/re-whitemark response.
