This person on tumblr made a slide show that is meant to be a humorous introduction to what D&D is about. It's pretty neutral in terms of edition, though it does have a lot of swearing (in case anyone is bothered by that). My partner, who is not a gamer herself, was laughing out loud to some of these jokes.
