Anderson Cooper Laughs Himself To Tears In Prancercise Segment (VIDEO)

Anderson Cooper laughed so hard on Tuesday's "Ridiculist" that he had to wipe tears away from his eyes.

The CNN host could barely keep a straight face while discussing his latest target: Prancercise, a fitness program described by creator Joanna Rohrback as "a springy, rhythmic way of moving forward, similar to a horse's gait."

Cooper started giggling as soon as he started talking about it. "I really -- I thought this was a "Saturday Night Live" skit," he said. "It's not."

But what really set him off was an informercial for a Korean fitness machine that entails a lot of pelvic thrusting — which he already been named to the Ridiculist in the past. After playing the clip, Cooper was wiping his eyes.
