In "Franklin & Bash," which premiered this month on TNT, two debauched playboys join a tony law firm and introduce their new colleagues to the joys of hot tubs and karaoke. "Harry's Law," which just finished its first season on NBC, features a zany, pistol-packing Kathy Bates, who starts her own criminal defense law firm. In "Suits," which debuts next week on USA, a guy without a college or law degree successfully masquerades as an attorney.
