One time on an airplane I was doing some erlang programming.  I had about 10 terminals and Textmate open.  After about half an hour I get a tap on the shoulder from the smoking-hot woman sitting behind and to the left of me.  She says, "Excuse me, but I find what you are doing to be utterly fascinating.  What is it?". I explain that I'm programming, and she asks if she can watch.  I said "sure", but I was so self-conscious that I couldn't get any real work done after that.  I just ended up flipping between Textmate and my terminals, typing random commands.  Sadly, I didn't get her number - we were both on a connecting flight to different cities.
