Chicago conservative radio host Erich "Mancow" Muller decided that there was only one way to silence critics of waterboarding, and that was to get waterboarded himself to prove that the technique isn't torture.
In a controlled environment Mancow was waterboarded, and lasted 6 seconds, despite claiming before hand that he'd last 30-60 seconds. But this is where it gets interesting, because an exercise to prove waterboarding isn't torture instead proved to Mancow that it was.
"It is way worse than I thought it would be, and that's no joke," Mancow said. "It is such an odd feeling to have water poured down your nose with your head back... It was instantaneous... and I don't want to say this: absolutely torture."
Here's the Mancow waterboarding video. Note some people may find the waterboarding scene distressing.
