It would have been a little more convincing if they'd bothered to use an apostrophe: Media Mogul's Body Discovered. Not to nitpick, but you want a media prank to work, you need to think like media people. They wouldn't forget punctuation.
From wikipedia:
"The nickname The Grauniad for the paper originated with the satirical magazine Private Eye.[109] This anagram played on The Guardian's reputation for frequent typographical errors, such as misspelling its own name as The Gaurdian."
