A misspoken word is not on the same level as not knowing where the most important battle of the Revolutionary war was fought. Not even close.
[pedant] Technically the Battle of Concord was fought hours before the start of the Revolutionary War, at least according to David Hackett Fischer... so it's disqualified.
As for which is most important, many opinions. I'd pick Saratoga, with honorable mention to Ticonderoga (1775), but it's subjective. [/pedant]
anyone who doesn't know that the Battle of Long Island was fought in Brooklyn, NY.....ain't know nuthin' about nuthin'.
