UPDATE Rob sez: "Yahoo, via Bill Mesfin and API, have a slightly better version of the Koko story. Of particular note:
"Her teacher, Francine Patterson, was at her side when the anesthesiologist prepared to put her under in the morning, and apparently Koko asked to meet her specialists."
"They crowded around her, and Koko, who plays favorites, asked one woman wearing red to come closer. The woman handed her a business card, which Koko promptly ate."
