Note to self: don't say stupid things when meeting important sciencey types.
Recent example: upon meeting very nice and normal professor man who had given a talk on chaos theory and the random nature of bread making (don't ask), the following fell out of my mouth... "Since you're kind of a Professor of Randomness, and I'm the editor of the Journal of Unlikely Science, I wondered if you fancied doing an interview?"
Learn from this. You could have said: "Hello Professor. I really enjoyed your talk. Could we do an interview. Would you? Oh, that would be lovely."
