A bizarre spate of television presenters dissolving into on-air gibberish has sparked claims that the U.S. military could be to blame. In four high-profile cases, the latest involving fast-talking Judge Judy, the presenters have started off speaking properly but have then descended into undecipherable nonsense - looking confused and unstable. The frequency of the 'attacks' - and the fact that recorded examples of the mental meltdowns have been popular on websites - has led to conspiracy theorists pointing the finger at shadowy government experiments. A popular theory being circulated online blames the U.S. Military's supposed research into using microwaves as a mind control weapon. America has never admitted conducting such research but proponents say the effects - produced by microwave signals stimulating the brain with fake images and voices - exactly mimic those displayed in the recent on-air breakdowns. Serene Branson's garbled Grammys report became an internet sensation, while WISCTV's Sarah Carlson suffered a similar meltdown in January. Judith Sheindlin, the fast-talking judge on Judge Judy, was taken to hospital ... after she began speaking a nonsensical string of words during a live recording of her courtroom TV show.
