You say you love unusual food?  Then this may be just what the doctor ordered.  The seventh annual Testicle Cooking Championship is currently going on in Serbia's city of Ozrem.  Local chef Ljubomr Erovic is the organizer of this offbeat festival that features both old and new recipes derived from the, well, scrotum.  In the Balkans, testicles are believed to accentuate a man's libido, and in Serbia they are commonly called "white kidneys".  High on the list this year are boar, camel, ostrich, and kangaroo testicles, mostly supplied by a local slaughterhouse.  While some vendors are offering roasted pig or lamb as "side dishes", one of he most requested dishes this year is testicle pizza.  You want fries with that?
