American Benjamin Miller was savagely gored while participating in the Carnaval del Toro (or "Carnival of the Bull") in Ciudad Rodrigo, near the Portuguese border -- one of the oldest bull festivals in Spain. 

I grew up on a farm working with cattle. Ours were much more docile than these bulls that are let loose. But I've seen the power of bull firsthand and I have respect for it.

If you need this kind of adrenalin rush to prove you're a man, you need to really think about your priorities. Getting in with a scared and upset bull might not be the best idea.
