Fact

Facts about facts
A fact is a mysterious thing, a floating globule of interest fludspluddling its way around the Thinkosphere. You can, in fact, see facts (thats one over there, looks like a turtle doesn't it). They are an incredibly tiny microllopullusite and a subspecies of the Knowlspledge. Facts provide an amount of intelligence, though just containing many facts does not make you clever, just a sort of walking Wikipedia (in the old days we would have said "walking slightly innacurate encyclopedia" see how we move with the times).

The Word Itself
The word 'fact' was first recorded in 1539. It originally meant 'an evil deed'- according to the QI "G" Annual's "Gremlins" page.
