Chefs compete at testicle cooking competition

Teams of chefs in Serbia have been serving up their best testicle-based dishes as part of the World Testicle Cooking Championship.

The event, amazingly now in its seventh year, see gonad gourmets creating the best meals they can from boar, kangaroo and donkey balls.

Delightful dishes on offer at the freaky food festival this year included testicle pizza and the ever-popular goulash style bulls’ testicles.

Visitors taste a selection of the meals before a judging panel decide on which ones really stand out.

Festival organisers also give an award to someone who has been "ballsy" over the past 12 months -- this year it wasn't the man who tried testicle pizza, but U.S. President Barack Obama.
