As anyone who watches Anderson Cooper's daily RidicuList segment knows, the best part is not so much the substance as when the host breaks out his signature giggle over some juvenile Butt-head-erism.

That's exactly what happened last night: While discussing the serious Easter tradition of Dyngus Day, Cooper came across the words "pussy willow" and became so overwhelmed with tee-hees that he had to step away from his desk, possibly forever. Mirth in check, Cooper eventually made his way back, but the snickers soon followed.

Watch the footage above, but be warned: Highly infectious laughter ahead.
