I don't know why exactly, but if you tell me something is your favorite, I want to know all about it - I want to know what it is, what you like about it, how it makes you feel, etc.  And I want to try it.  I am most fascinated with a person's favorite meal.  Now, I'm not a huge fan of reality television or celebrity culture, but I feel a television show, or segment, or even a webcast, in which an amiable, somewhat comedic host interviews a celebrity while preparing and/or simply dining on said celebrity's favorite meal would be an enjoyable, successful series.
