The website Cracked.com reports on 6 Famous "Frivolous Lawsuit" Stories That Are Total BS. Undergraduate students are very familiar with the Cracked website which provides a healthy dose of humor and sarcasm to the youger generation. Warning! Cracked does not hesitate to express its ideas in language that you would otherwise try to avoid in class. So, I wouldn't put this up on the projector, but I might assign it on a syllabus.
