Denver's Channel 7 news made a HILARIOUS mistake on Monday, while they were reporting on the affair between General David Petraeus and his biographer, Paula Broadwell.

--During their segment, they showed the cover of the book, which is called "All In".  But whoever grabbed the image off the Internet didn't look at it very carefully . . . because it was a Photoshopped version with a much more GRAPHIC title.

--It said, quote, "All Up In My [S-word]" . . . that rhymes with "hatch."  (--Search for "ABC Runs Fake Cover of Petraeus Biography."  The book cover pops up at :09.  The video quality is terrible.  Here's a screenshot.)
