This blog post (via metafilter) is about the silly names that radio presenters have on NPR in the States. No idea. But the method for determining your 'NPR' name is funny:
You take your middle initial and insert it somewhere into your first name. Then you add on the smallest foreign town you’ve ever visited.
Mine would be Almison Lautrec which is a great name isn't it? Well, for some definitions of 'great'. I may use it as a pseudonym.
