It's National Punctuation Day! This one is for grammar geeks only. In honor of this year's celebration, The New Yorker magazine is sponsoring a contest:
"The rules: Write one paragraph with a maximum of three sentences using the following 13 punctuation marks to explain which should be 'presidential,' and why: apostrophe, brackets, colon, comma, dash, ellipsis, exclamation point, hyphen, parentheses, period, question mark, quotation mark, and semicolon. You may use a punctuation mark more than once, and there is no word limit. Multiple entries are permitted.
"In short, persuade us that your favorite punctuation mark should be the official punctuation mark of the President of the United States."
Submissions are due by September 30, 2012. Read the rules here.
This website features several photos of incorrectly punctuated signs, include a few submitted by me. Below is one gem, selected by the website owner as "The Dumbest Sign of the Year."
