The Wall Street Journal studied grammar on the fan boards of various NFL teams. It turns out that the fans of the Washington Redskins commit more grammatical errors than any other team after analyzing 400 different types of spelling, grammar and punctuation mistakes.
On the flip side the leagues’ best team for grammar was the Detroit Lions, whose fans had a mere 4.2 mistakes per 100 words. I guess that number was to be expected as there are far fewer grammatical rules when it comes to expletives.
