Billionaire and activist investor Carl Icahn took his Yahoo obsession to the airwaves with a phone-in interview on CNBC's Fast Money yesterday afternoon. In my attempts to distill the over twelve-minute, rambling dialogue with the anchors on the show, the most interesting thing was how guarded and halting Icahn was about his intentions — he revealed little that he, or one of his assistants, hasn't brought up in his many open letters and other lobbying to unseat CEO Jerry Yang, or answer the question "If you succeed in your proxy battle, who says Microsoft will buy?" So with no money quotes to go with, I threw in everything else.
