Tuesday Question: What's the Grossest Thing You've Ever Eaten?

So, what's the most hideous thing you've ever knowingly swallowed, food-wise? Do you crave the nasty bits? We'd love to hear your story. And to get the old creative juices flowing, here are a few images of delectable dishes served at the Olympics food concessions in China this year. These pics are making their way around the 'net, in case you missed 'em, and we have no idea who took the photos -- but whoever you are out there, thank you for sharing.
