(Toledo, OH) First there was Wikipedia, the collaborative encylopedia that has become a go-to source of basic information on almost any topic.
May I introduce to you Uncyclopedia, "an encyclopedia full of misinformation and utter lies." The website also bills itself as the place that "puts the 'psych!' in 'encyclopedia.'"
Local readers might check out the entry for Toledo, OH to get an idea of the frivolity and hijinks that abound at Uncyclopedia. Another example of Uncyclopedic insanity can be found at the entry for England.
Not funny enough for you? Then get in there and edit, Bubba!
