A rather conservative radio host out of Chicago (aka Mancow) gets waterboarded:
Fast forward to about 2 minutes in to see the actual waterboarding and his reaction. A choice quote:
"I wanted to prove it wasn't torture," Mancow said. "They cut off our heads, we put water on their face...I got voted to do this but I really thought 'I'm going to laugh this off.' "
The upshot? "It is way worse than I thought it would be, and that's no joke," Mancow told listeners. "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."
