Debating Wikipedia's accuracy

A lot of people ask on Yahoo Answers whether or not Wikipedia is reliable or accurate. A recently reran Saturday Night Live skit from last season really puts that question into perspective: A straight man (Jason Sudeikis) pretends to be gay so he can be the roommate of a beautiful woman (yes, I think Casey Wilson is beautiful). To explain an erection that she felt, the man creates a Wikipedia article on "boner-plasia." When he's finally forced to admit that not only is he a straight man, he also created the Wikipedia article on "boner-plasia."
