NPR's Science Friday with a (Second) Live Studio Audience

If you listened to Science Friday on NPR's Talk of the Nation today, you may have heard Ira Flatow mention a question from "Prospero Linden"— that was me. I was there, live, along with a 30 or 40 other people...

"Be nice to Shelly! She's cute, and she likes birds!"

Uh, no. Look, we're all human, and we all have eyes and brains and things, and as such one may as well admit that if you look at the pictures that Shelly has of herself on her blog, there's a...
