How to talk to your kids about animal sex

I have this great teenage memory of standing next to my father at the Baltimore aquarium, as we both attempted to stridently ignore the gigantic walrus penis that was flopped out right in front of us. I assume a lot of people have similar zoo memories. But, if Lisa Britton has her way, children of the future will at least have some interesting facts to go along with the familial awkwardness. She's the new "birds and bees consultant" at England's Chessington World of Adventures zoo. Her job: Explain copulating animals to kids (and help their parents get past the deer-in-the-headlights response). The Guardian has a short profile.
