Bit off-topic this, but it is Friday afternoon. This story is doing the e-mail rounds, about a too-dumb-to-be-true contestant on the US version of Who Wants To Be A Millionaire?, who chooses "elephant" instead of "moon" when asked which is larger.
I am a born skeptic, and didn't believe this could be true. Sure enough, it isn't, it's a hoax. Hoax-slayer, as ever, has the full story.
