My investment advisor promised that a diverse portfolio would protect me from market swings. He was wrong. 
Interscope Records apparently thought diversity was a good idea, too. A manager of some Interscope rap guy named The Game ( I never listen to rap–life is too short for self-inflicted pain) was shipping tons of cocaine in road cases. The cases were delivered and picked up at Interscope. Diversity, indeed!
