"AMES, Iowa -- As the car pulled into the parking lot of a Starbucks, William Sanford Nye unknotted his trademark bow tie and slipped it off."
"'This might buy us a couple of minutes,' he said.
Roughly two minutes later, before his drink was ready, he was recognized anyway. Two awed young women approached to ask if he was really Bill Nye the Science Guy. Like more than a dozen other college students who would approach him over the next several hours, they asked if they could take a picture with him. He smiled, took a proffered iPhone, scooched the students in and, in a practiced gesture, stretched out his arm to take a shot of the three of them that you just knew was totally going on Facebook."
