Before signing off each night, Anderson Cooper concludes AC360 with a segment called the "Ridiculist," during which he comments on some trivial bit of news or pop culture. It's a chance for Cooper to show off his less serious side, but he took things to a whole new level tonight when his own joke about French actor/plane urinator Gérard Depardieu caused him to giggle uncontrollably for a minute or so on live TV. Video of Andy's laughing fit is above.
