Wendell Gauthier loves to smile. Sure, the most renowned class-action lawyer in New Orleans possesses many other trademarks. He has full-bodied Atticus Finch hair, and he's tailored like a mogul from Milan. With a soft Cajun accent, he's a fount of country-lawyer malapropisms (he says his old friend Edwin Edwards, the frequently indicted former governor of Louisiana, has a "photogenic mind"). But Gauthier's defining characteristic is the infectious, perpetual, coprophagous grin. Indeed, an opposing lawyer once objected to a judge that Wendell Gauthier smiled too often. With his track record, who wouldn't?
