Erica Jong

What I don't like about Guinevere is the fact that she can't control her passions and urges. She gets herself into quite a love triangle, and quite a web. Personally, I find that very difficult to relate to. But, it wouldn't be interesting, if she did everything right.

I'd been doing projects outdoors for the public. I made pigeons eat geometry by putting bread out in rhomboids and triangles. I don't know if this activity made sense, but the work was available.

Funny, reely," he said. "You spend your whole life goin' to school and learnin' stuff, and they never tell you about stuff like the Bermuda Triangle and UFOs and all these Old Masters running around the inside of the Earth. Why do we have to learn boring stuff when there's all this brilliant stuff we could be learnin', that's what I want to know.
