Overview: A late-night talk show isn't a late-night talk show until somebody eats bugs. On Tuesday's show, ""Unscrewed"" gets its official stamp of approval when both Martin and Laura chomp down on some juicy arthropods with the president of the Bay Area Bug Eating Society (BABES). Also on tonight's show, Judy's most provocative Porn Tip, ""Dark Tipper"" gets desktop revenge, and a monkey drinks its own urine. How's that for family entertainment?
