The Simpsons: Season 12, episode 6
Early in this episode of The Simpsons is a brief scene that is a wonderful illustration of the problem of trusting unknown Internet sources. Homer wants to create a web page, but is having trouble coming up with material. He decides to rely on an unfounded rumor that the Bart has heard. (This scene happens shortly after the tire crashes through the window.)
The rest of the episode has other illustrations of problems that can be caused by relying on Internet sources.
The episode is available for free with a cable or DirecTV account number at SimpsonsWorld.com.
