I think LWers may be intrigued...
Tim McGrew, author of this excellent annotated bibliography on Bayesian reasoning, recently co-authored with his wife Lydia a Bayesian defense of the resurrection of Jesus. I interviewed Lydia for my podcast, here. Atheist Richard Carrier has leveled some objections to their article, but his objections are weak.
Have at it.
I claimed to be from the planet Myridia (spelling ambiguous, I never wrote it down.) I believe I said it was something like seven light years away (if not seven, then some single digit number,) and that it was part of a relocation project due to overpopulation.
I don't remember if I ever talked to my parents or teachers about it, but they knew me well enough to figure that it was something I'd do for entertainment, rather than a delusion or cry for help.
A majority of my peers didn't pay much attention, and probably figured it was just a story I came up with, but a considerable number took it quite seriously, and while I can't say they weren't gullible in light of what they actually fell for, some of them were considerably smarter than the average student. I tailored my lies to hold together on a much higher level than most students were likely to address them at, and think it flattered their intelligence to think that they had investigated the claims further than others, and reasoned their way to a conclusion contrary to what the majority believed.
Some of the students were just idiots though.
