world's most successful lawyer

Sir Lionel Alfred Luckoo (1914-1997), according to the Guiness Book of World Records, as a result of his obtaining 245 consecutive murder acquittals as defense counsel. Normally, one doesn't aspire to getting into the Guiness Book -- it usually means you have some freakish tendencies/abilities and no life. But, I wouldn't mind holding this particular record. I also wouldn't mind being knighted like Sir Lionel Luckoo....

Most noteworthy, however, Sir Lionel became the inspiration behind the name of attorney Lionel Hutz on The Simpsons. (The Hutz character was retired, out of respect, after the shocking death of Phil Hartman, the character's voice.)
