There is something transcendently idiotic about running through the streets with a group of large, angry bovine. It's exactly what makes the annual running of the bulls in Pamplona so darn interesting to everyone from "Jackass" fans to Hemingway scholars.

Today marked the opening day of the event and here are the stats so far: 13 injured, including two concussions, 10 people in need of treatment for cuts and bruises, one collapsed lung, one ruptured spleen and an undetermined number of broken ribs.

Any way you break those numbers down, no one was gored, so you've got to question the bulls' desire. Take a look at some of the pics from the festivities and let us know what you think.
