I like to chew on knotty questions, but every now and then I run into one that even I can tell is just flat-out beyond my reach.
For example, from an email received today:
I am Dr. Marc Schneider and I work for Multilingual Search Engine Optimization Inc. in Washington DC ( Tel: 1-202-558-2504) - I would like to speak with the person in charge of your international clientele. Who is my contact? Who should I speak to??
