A couple of weeks ago the New York Post screwed up Yankees' pitcher A.J. Burnett's E.R.A. by placing a colon rather than a decimal point in the number. The other day the Post forgot to place an apostrophe in a contraction that appeared in a review of Conan O'Brien's first episode as host of NBC's Tonight show. The mistake was submitted by the Proofreader's good friend, and a very funny guy, Adam Wade.
The mistake appeared on page 34 of the June 2nd edition of the paper, in the third-to-last line of the article, as you can see highlighted in the picture above. In a review that critiqued Conan for being "unfunny," the Post, in a funny display of incompetence for a professional news publication, made a stupid error . The Post forgot to type an apostrophe in the contraction won't, which resulted in the word "wont."
This mistake was of the double-threat variety, as it appeared in the printed paper and, as of this post, still exists online as you can see here or in the below screen shot.
The Proofreader thanks Adam Wade for submitting the mistake.
