World's Craziest Fools is a clip show made by Roughcut TV for BBC Three, presented by Mr. T. It showcases clips, sometimes viral, of people making themselves look like "Fools" (a reference to Mr. T's catchphrase), often by accident. Many clips were from CCTV footage. The videos were shown in different categories such as "Parking Fools", "Drunk Fools", "Criminal Fools", and "Fools jumping off things they shouldn't be jumping off of". As would be expected, some categories see more entries than others, and the categories that feature episode-to-episode are not bound to a predetermined structure.
Some segments of the show are animated to tell the story of a fool or fools of which they have no footage. The animation was done by Big Red Button and Ben and Will Animation. Sometimes, real audio from the event was added to the animation. For example, a police phone call.
Every episode contains a 1-2 minute "Top 5" countdown segment, such as places not to park. This animation was done by Christopher Poole and Plastic Horse.
The first episode aired on 6 June 2011 on BBC Three receiving a large 756,000 overnight audience viewing. A new episode aired on Monday nights at 10:30pm. The show was repeated often throughout the week, from Tuesday to Monday - 7 showings in total. The second episode received a respectable 608,000 in the overnight ratings. However, by the fifth episode, overnight ratings came to a series high peaking at 848,000. Ratings stayed strong for the remainder of the first season. It was also one of the most watched BBC Three shows on BBC iPlayer.
On 3 February 2012, BBC Three announced that the show would return for a second series. It started airing on 7 January 2013 at 10:00pm.
