Browsing through the hilarious pages of FailBlog.org during rare moments of downtime has become something of a tradition here at TechCrunch. The site painstakingly chronicles some of the funniest (and bizarre) screwups from around the web and real life, ranking them according to just how badly they fare on the Fail spectrum. And today, the Guinness Book of World Records has managed to reach new levels of Epic Fail.Earlier this week FailBlog posted a screen-grab (see below) of one of the entries on Guinness detailing the "Most Individuals Killed In A Terrorist Act", which included a link inviting viewers to "Break this record". It was a classic case of Fail, likely caused by either a side-wide template that included the link or an editor who fell asleep at the wheel. But rather than just simply fixing the issue, apologizing, and moving on, Guinness has decided to dig a nice, big hole for itself by threatening FailBlog with a lawsuit for featuring the Guinness World Records logo without authorization. This morning FailBlog posted a note to its site (appropriately titled 'OMG U FAIL SO HARD') with a screenshot of the threat, along with the site's response.
