Where/When: Rock Creek Lodge, Montana, USA: September
Assuming you've escaped Kirkpinar with your plums intact, you might want to check out the world's largest testicle festival. Not only can you taste delicious deep-fried bull's testicles and ogle women in the wet t-shirt competition, you can also get bladdered on the Bull Snort Brew. Nuts - quite literally.
Freakiness rating: High - Putting yourself at the mercy of drunken hillbillies is a recipe for disaster. Just remember - they won't hear your cries up in the Montana hills.
