Fact or Fiction is a promotional podcast of HowStuffWorks.com. It is a rather new production and that probably explains why it doesn't show up on the HowStuffWorks.com website, but the podcast can be found in iTunes.
Under the motto History stuff for the history buff the cast delivers short episodes of less than five minutes in which there is a scripted dialog between expert Candice and counterpart Joshua, who comes up with the question. The question involves invariably some tidbit of popular historical assumption, to which Candice must reply whether it is fact or fiction. The subject corresponds with an article on the main website. Was there a curse on the tomb of Tut ankh Amon? Were the American colonists drugged during the Salem witchcraft trial? And so on.
This podcast is short, anecdotal and entertaining - very light stuff, for the very light buff.
