Familiar metaphorical smell snagged hosting job for Tyson

In a Q&A with The Boston Globe, astrophysicist Neil deGrasse Tyson (right, NOVA photo) reveals how he came to host NOVA ScienceNOW. "After their inaugural season, in which I had been interviewed multiple times, they needed a new host," he recalled. "They knew what I looked like, what I smelled like--metaphorically--and so my name sort of rose to the top." And who's the toughest interviewer of all his ongoing media appearances? Stephen Colbert of The Colbert Report, followed by Jon Stewart of The Daily Show, both on Comedy Central.
