http://en.wikipedia.org/wiki/SicQUOTE
[sic] or (sic) (Latin for "thus") is a bracketed expression used to indicate that an unusual spelling, phrase, or any other preceding quoted material is intended to be read or printed exactly as shown (rather than being an error) and should not be corrected.
When found in a French document, (sic) stands for "Sans Intention Comique" (without comic intention) meaning that even if the preceding text could be understood as funny, it was not meant to be.
