This was not only on the internet... but an actual publication. Therefore, it must be true. After all, its the worlds only reliable newspaper. They said so and that also must be true.
Actually this first appeared in one of those old email chains before the Internet became mainstream. Remember those? Got em all the time and good for a laugh. But still a huge number of people believed it no matter how many times it was disproved to be a hoax. However, these days, its easy to make such things that include fake 'proof' (many sites do it for you) and doesnt help when distributed by sites that never check whether something is bullshit, including big name sites with huge audiences, and even then will do nothing when it is shown to be that.
And then you get complaints by well known people believing such things getting on the air and complaining about censorship and vast conspiracies when taken down. To the point that some in power try to change laws because of 'it'. Whatever 'it' is, pick one. Its stuff like this that destroyed any faith I had in the intelligence of this country.
