Think about it: If it weren't for testicles, you wouldn't be here. That's part of the reason why the idea of biting into a "prairie oyster" makes us wince a little bit. How could you do that to another guy (even if he is a bull)?

The folks at the Black Gold Cattle Company's Testicle Festival in Colorado have no such issues. In fact, they encourage people to "have a ball." The two-day event raises almost $30,000 each year for charity and pays homage to cowboy traditions.

There are the usual rodeo acts and branding competitions, but the main delicacies on the bill are the deep-fried Rocky Mountain Oysters (bull testicles). Also called "cowboy caviar," the balls are served with a cheeseburger and a drink as part of the five-dollar "Sack Lunch Special."

The festival bought 250 pounds of bull testicles from a meatpacking plant for this year's event, and the meat was prepared and cooked by a "nut specialist," who dips the balls in a beer batter before throwing them into hot lard for five minutes and serving.

Question raised: Would you eat bull balls? What's the grossest thing you've eaten?
